What Should You Know About The Right Hand Rule MCAT?

Right hand rule MCAT is the thing you should deeply understand before the process of taking this test. Follow this article to find out beneficial information.

June 18, 2022

Right-hand rule MCAT is one of the most important parts of the MCAT exam. Successfully passing this exam portion will help you maximize the possibility of acing this test. In this article, we will provide you with beneficial information about this segment, as well as several considerations for it.

Right-hand rule

The right-hand rule is used by scientists as a mnemonic to help them remember which way permanent magnets should be oriented. To memorize the mnemonic, make an L shape with your thumb and the first middle finger of your right hand and hold it there. Finally, put your middle finger at a 45-degree angle to your index and middle fingers as the last step.

right hand rule MCAT

The right-hand rule is a shortcut for remembering which direction things should be pointing in the presence of magnetic fields and the pressures they impose on moving electric charges, according to the basic rules of physics governing magnetic fields and the forces that they exert on moving charges. Despite the fact that it is not rare for scientists to mistakenly utilize their left hand, it is conceivable for them to anticipate magnetic force in the opposite direction from what it really is!

Moving charges

When charged particles are fixed, magnetic fields have no influence on them; nevertheless, when charged particles begin to move, the magnetization exerts a force on them. The lines, on the other hand, are not aligned with the direction of the field’s force on the charged particles. Rather, it seems to be as follows:

right hand rule MCAT

The right-hand rule may be useful in recalling the contents of this figure. With your pointer finger pointed in any direction except the direction of the magnetic field, you will hold a pen in your hand with your thumb pointing in the direction of the magnetic force pushing on any positive charge passing through the pen. Because electrons have a force that points in the opposite direction of your thumb, you cannot manipulate them with your thumb.

Current in a wire

Conventional current refers to the flow of positive charges in a wire, and this is what we mean when we say “conventional current” in the context of electricity. A magnetic field may have the same impact on wires as it does on a single moving charge, but it is important to remember that current is nothing more than a stream of moving charges flowing in the same direction.

right hand rule MCAT

It is possible to tell which direction a wire is moving in a similar manner to how we used the right-hand rule to discover which way a device was charging and discharging. We may use the pointer, middle, and thumb of our right hands to determine which way a wire is going. In the standard x, y, and zx coordinate systems, the thumb points in the positive xxx direction, the first finger points in the positive yyy direction, and the middle finger points in the positive zzz direction, all in accordance with the right-hand rule.

A magnetic field generated by a current in a wire

The movement of charges is influenced by magnetic fields, but magnetic fields may also be used to cause the movement of charges. With the help of the second right-hand rule, we can determine the magnetic field produced by moving charges, as well as the associated electric current. Figure 1 is an illustration of how the magnetic field is formed by a current spiral around a straight wire. By curling your fingers and pointing your right thumb in the direction of the current, you may determine how much current is flowing through the wire. It will be forced to bend your fingers in the same way as the wire was bent by the magnetic field that surrounds the wire.

right hand rule MCAT

Alternatively, if you already know which way the magnetic field is pointing, you may use the inverse of this process to discover which direction the current is flowing through the wire. Curl your index and middle fingers around your index and middle fingers once again while pointing your thumb in the direction of the magnetic field once more. Using the circular motion of your fingers, you may be able to establish the direction of the current that caused the magnetic field to be generated in the first place this time.

right hand rule MCAT

When electricity is sent through a coil of wire, which acts as the conductor for an electromagnet, magnetic fields are produced as a consequence of the current passing through the coil. As a result of its long axis, it produces magnetic field lines that all point in the same direction as the rotational axis. In the case of coiling right-hand principles, circular magnetic fields and straight lines of current are produced as a result, and they may be distinguished by the following characteristics: With the help of the right-hand rule, it is possible to study both cases in the same amount of time.

Current-induced magnetic force

Moving charges in a normal current are all positive, which indicates that the current is moving. When a conventional current travels over a conducting wire, electromagnetism pulls the wire in the opposite direction. In order to determine the direction of the force acting on the current-carrying wire, it is possible to use the right-hand rule. Here, the magnetic field direction is represented by your fingers and thumb; the conventional current flow is represented by your thumb, and the wire path is represented by the palm of your hand (force).

According to the definition of current flow as the movement of positive charge carriers, the conventional current is traveling up the page in the above illustration (conventional current). It is also possible to portray the same current-carrying wire as having a current with negative charge carriers moving down the page, in the same way, that a conventional current is made up of positive charges. Despite the fact that the currents are moving in opposite directions, a single magnetic force is identified to be operating on the wire.

Consequently, the force produced by the flow of positive or negative charge carriers in the preceding image is the same as in the previous figure. Whenever the right-hand rule is applied to a conventional current direction, it causes the magnetic force to be orientated toward the right. As a consequence of using the right-hand rule, the flow of negative charge carriers implies that magnetic force is directed to the left; nevertheless, the negative sign reverses the conclusion, implying that magnetic force is directed to the right.

Because we are dealing with two separate physical situations, flowing charges in two unique lines, one with positive charges and the other with negative charges, will not create the same magnetic forces. First, positive charges are traveling up the page, implying that negative charges are moving down the page, and vice versa.

When we use the right-hand rule, we may be certain that the magnetic force will point in the appropriate direction. Because the negative charges are traveling up the wire, the positive charges in the second wire are flowing down the page in the first wire. As a result, according to the right-hand rule, the magnetic force is moving to the left.

Right-hand rule for torque

Torque problems are usually the hardest for first-year physics students to understand. In the lucky case of the right-hand rule, torque may also be employed in this manner. When dealing with torque problems, a good rule of thumb is to point your right hand towards the direction of the vector field (r or d), then rotate your fingers and thumb to face the force.

Right-hand rule for a cross product

A cross product, also known as the product of a vector, is produced by performing an ordered operation on two vectors, a and b. When you take the cross product of two vectors, you will find that the cross product is orthogonal to both of the original vectors. Given the fact that there are two possible pathways for a cross-product vector, it is required to use the right-hand rule. When working with cross objects, make sure your fingers and thumbs are at proper angles. In the illustration below, point your pointer finger at vector a, and your middle finger toward vector b: Axb vector product will be shown by your right index finger on your right thumb (vector c).

Right-hand rule for Lenz’s principle

Lenz’s Law is governed by the right-hand rule. To summarize, when the magnetic field in a closed conducting loop changes, the direction of the induced current is such that the second magnetic flux created by the induced voltage opposes the initial change in the magnetic field that produced it, as stated by Lenz’s law. What does this entail in concrete terms? Let’s have a look at this.

When the magnetic flux across a closed-loop conductor changes, a current is generated. Because of the presence of this second magnetic field, the induced current acts in opposition to the original shift in flux that caused it. It is governed by the strength of the magnetosphere going through a wire coil that the magnetic flux is generated. This equation illustrates how the strength of a magnetic field, the size of a coil, as well as the orientation of the coil in relation to the field, all influence magnetic flux in a circuit.

It is necessary to first determine if the initial magnetic strength is increasing or decreasing in order to realize how Lenz’s Principle may affect this system; otherwise, we will not understand how Lenz’s Principle might affect this system. It is the closeness of the magnetic north pole to the Earth’s magnetic field that causes an increase in the existing magnetic field. Consequently, the induced current and associated magnetic field will diminish the magnetic field created by the original magnetic field in order to counterbalance this rise.

A consequence of this is that the primary and secondary magnetic fields will travel in opposite directions of one another. Whenever the present magnetic flux diminishes, the induced current and magnetic field that it creates counteract the weakening by boosting the current and magnetic field. A magnetic field created by this process will be aligned with the magnetic field induced by the initial magnetic field.

Before using the right-hand rule to Lenz’s Law, you must first determine whether the magnetic field is increasing or decreasing in strength. It has already been noted that the magnetic field lines created by magnets migrate from the geomagnetic pole towards the interior of Earth. if the magnetic flux is increasing, the strong magnetic component of the magnetic field will move in the opposite direction of the magnetic field direction.

A decrease in the magnetic field in the loop will result in an increase in the produced magnetic field component in the same direction as the drop in the magnetic field. Then, using the variations in the magnetic field’s induction, curl your fingers and you’re finished! When the induced current strikes your fingers, they will point in the same direction as the induced current.

Consider the following questions before you answer: an MRI uses a magnetic field

The patient must be placed in a very stable magnetic field in order to do an MRI, which is used to align the individual protons of water molecules in order to picture the patient’s whole body. The density and structure of distinct biological components are mapped using a very little change in the field’s alignment, which is the first step in the measurement procedure for that component.

A very strong magnetic field is required for fundamental magnetic resonance imaging (MRI) just in one direction: along the axis of an object. Magnetic resonance imaging (MRI) is used to diagnose and treat patients. A big magnetic coil around the patient’s body, while the patient is getting treatment, maybe conceivable with the device if it is designed correctly. According to the right-hand rule, a current that flows in a spiral around the patient’s body generates a magnetic field that points straight down the patient’s spine.

Let’s get started with our free MCAT practice test to enhance your chance of passing your actual exam with a high score on your first attempt.

What is an MCAT tutor?

An MCAT tutor assists the students in studying for the Medical College Admissions Test, which is a requirement for medical school admissions. Your responsibilities and duties differ based on the position and company. You might work as a freelance tutor, working with clients one-on-one to drill them on specific areas of the test where they are weak.

Tutoring for a large corporation might mean hosting group seminars to provide general testing tips.  You could also tutor an online audience. However, all tutors determine which parts of the test your client requires assistance with and develop strategies to help the student prepare for the exam and achieve the highest possible score.

Furthermore, a private tutor assists students in learning basic Medical College Admission Test concepts in order to support them throughout a complete school year Medical College Admission Test course. Students generally require assistance with additional support concepts such as math, physics, science, and others. A private tutor, regardless of the subdiscipline of the Medical College Admission Test they teach, is expected to be well-rounded in order to support the entire student’s learning needs.

What are the requirements for working as an MCAT tutor?

Working as an MCAT tutor has a variety of qualifications and requirements, but you must have taken the MCAT and received a very high score. In addition to test-taking skills, you must have a bachelor’s degree and vast knowledge of MCAT subjects like biology, chemistry, and math. The ability to assist students in managing their own learning as well as effective written and verbal communication are essential skills. Prior teaching experience is also helpful.

How to become an MCAT tutor?

It’s easy to become a tutor if you enjoy teaching others and love Medical College Admission Tests. To teach kindergarten and middle school, you’ll need a high school degree at the very minimum. Depending on the level, of course, you wish to teach, you may need a degree in a specialist subject for higher-level Medical College Admission Test courses.

The initial step is to choose which subjects you want to tutor. Then decide the age groups and grade levels you’d like to teach. Learn the curriculum for various grade levels as well as the key concepts. Finally, create your own teaching methods and tools, and as you gain more experience dealing with students, you will eventually build your own materials.

How much do MCAT tutors get paid?

Medical College Admission Test tutoring fees vary as tutors determine their own pricing rates and schedules. The hourly pay rate for MCAT lessons and tutors is $30. You can expect to pay $15 to $150 per hour for an MCAT tutor to educate you on how to improve your MCAT score. The average price of MCAT lessons varies substantially depending on location (including zip code), subject expertise, session length, frequency of sessions, online vs. in-person education, and many other factors.

Tutors have the flexibility and freedom to create their own fees in order to be compensated properly. New tutors frequently set reduced charges to help them establish a clientele and obtain a few positive reviews to help them stand out.

It takes time to become a great tutor, but it’s well worth it because it can provide a full-time income or act as a valuable source of supplemental income. You have complete control over your choices and freedom. Take the time to find out how much other tutors in your region charge based on their expertise and education levels.

How Much Chemistry Is On The MCAT? The Full Guide 2022

How much chemistry is on the MCAT? Here's all you need to know about MCAT general chemistry questions, as well as tips for improving your score.

June 17, 2022

The MCAT is the most essential exam you’ll take before applying to medical school, and doing well on it may considerably boost your chances of being accepted. The MCAT is undeniably the most demanding and longest exam you’ll take before medical school, in addition to being the most significant exam, you’ll take.

On the MCAT, many premed students are struggling with general chemistry problems. MCAT chemistry questions can be frustrating, with seemingly hard math problems and equations that you can’t seem to recall.

So, how much chemistry is on the MCAT? 

Chemistry, in addition to accounting for the bulk of the MCAT Chemistry and Physics part, also accounts for 35% of the MCAT Biology section, making it the second-most tested topic on the MCAT behind biology.

As a result, in order to do well on the MCAT, you must have a firm grasp of the concepts and categories of chemical knowledge assessed.

We’ll go over all of the chemistry concepts evaluated on the MCAT, as well as tactics and study advice to guarantee you ace all of the chemistry the AAMC has to offer.

How much chemistry is on the MCAT?

The Chemical and Physical Foundations of Biological Systems (CPBS) portion, sometimes known as the Chemistry and Physics section, is, of course, dominated by chemistry. In fact, chemistry makes up more than 70% of this section:

how much chemistry is on the mcat

This part of the MCAT evaluates your ability to answer problems based on your understanding of fundamental concepts, scientific investigation, and reasoning abilities. Because the CPBS part is the first you’ll see on the MCAT, it’s critical that you breeze through it. CPBS, like every other science-based portion of the MCAT (excluding CARS), consists of 59 questions that are divided between discrete or one-time questions and passage-based questions. You will have 95 minutes to finish this subject, same as the other scientific sections of the MCAT.

Chemistry is also important in the section on Biological and Biochemical Foundations of Living Systems (BBLS):

how much chemistry is on the mcat

With chemistry accounting for about a third of the CPBS section and a third of the BBLS section, it’s difficult to overestimate the relevance of these many modalities of chemistry when it comes to learning. Because the CPBS component of this tutorial is our major emphasis, biochemistry will only be mentioned on occasion. Regardless, with general and organic chemistry accounting for 10% of BBLS questions, most of what we explain here will apply to the MCAT chemistry questions in both sections.

An ultimate guide for determining which chemistry concepts you should review

The MCAT’s wide range of chemistry knowledge might make planning a study schedule seem intimidating. Fortunately, there are certain fundamental best practices that can help you successfully organize your energy and time.

Taking a full-length MCAT diagnostic test is always the first step. There’s no way to tell for sure what your baseline knowledge is until you’ve imitated the exam process and forced yourself to think under pressure. This involves doing your diagnosis in a quiet room with only a copy of the periodic table and some blank paper.

While various prep businesses and question banks offer a variety of tests, the greatest option for your initial diagnostic is one that comes directly from the horse’s mouth.

As you look over your findings, go through each erroneous answer slowly and make a note of which of the aforementioned categories it belongs to. As you do this, patterns should develop, as erroneous responses are frequently found within a topic such as:

  • Problem-solving
  • Interpretation
  • Data analysis
  • Chemical formulae
  • Fundamental concepts in chemistry

You may then plan out when you’ll start preparing for the MCAT in earnest. We recommend starting no more than 6 months ahead of your preferred examination date, as doing so will likely result in you losing everything you learned earlier in the process.

After you’ve committed to an MCAT study plan, you may start fine-tuning your sessions to include MCAT chemistry questions, MCAT physics equations, and MCAT biology questions in varying quantities based on your needs.

Question banks like UWorld can also assist with this since they allow you to focus on certain subtopics and evaluate explanations and rationales after erroneous replies. Although we don’t advocate taking practice examinations from organizations like UWorld as an initial diagnostic test, they can be useful if you need to build or restore subject-specific muscles in biochemistry, organic chemistry, and other subjects.

Nonetheless, around the halfway point in your preparation, we recommend taking another of the AAMC’s mock MCAT examinations to offer an updated diagnostic baseline. As usual, the more input you get, the better, so talk to an MCAT teacher or prep service to see if you may benefit from some additional professional advice and comments.

It’s better to seek this assistance before the halfway point in your schedule, but if things are very challenging at that point, you’ll still have enough time to benefit from further assistance before the big day.

As you near the end of your MCAT preparation, you’ll want to shorten your review sessions and focus on more practice questions, elongating your sessions to begin to approximate the arduous time of the MCAT.

With the various tasks you’ll have in regard to your undergraduate studies, this might be challenging, so aim to reduce additional stress and scheduling complexity as much as possible during the last month or two of your plan. To earn a decent MCAT score, you will need to temporarily sacrifice or at least limit your social interactions in order to optimize your studying.

MCAT Chemistry questions: How to prepare

There are no trick questions

Throughout the test, the more nervous section of your mind will gleefully remind you that no question is simple and that if an answer appears simple or clear, you’re either thinking about it incorrectly or don’t understand it. Slow down if this tiny goblin appears while you’re studying or taking an exam.

The most prevalent cause of incorrect answers is rushing, even if you’re a seasoned scientific student who has carefully prepared for months before exam day. Most seemingly difficult—even unsolvable—questions are actually rather simple.

The MCAT has some tricky questions, but the test creators aren’t trying to fool you with phrasing. Reread a question if your initial impulse is to think of it as a 400-level midterm brain-melter, and believe that the exam isn’t attempting to trick you into answering poorly.

The study material for application rather than memory

When studying for the MCAT, time is incredibly precious. As a result, rather than memorizing knowledge, you should study it for application to practice passages and unique circumstances that the MCAT may throw at you.

The MCAT will almost never require you to recite a random chemical fact. Instead, the MCAT will give you a truncated scientific article in the form of a passage, ask you to critically assess it, and ask you questions that require you to connect your outside knowledge with the passage’s expertise.

So, what does studying content for application rather than memorizing imply? When studying each MCAT general chemistry subject, think of three different ways the MCAT may test you on that information. Consider the case of nucleophilic acyl substitution.

Many students become nervous when they hear the phrase nucleophilic acyl substitution since the reaction might take many distinct forms. In acidic vs basic circumstances, for example, the reaction appears slightly different, and the nucleophile and the leaving group can take a number of forms. The general principles behind the diverse responses, however, are the same:

1) A carbonyl carbon is attacked by a nucleophile.

2) Electrons are transferred to an oxygen atom, which now has a negative charge.

3) The electrons then return to the oxygen atom to re-establish the double bond.

how much chemistry is on the mcat

What are three ways the MCAT may put you to the test when it comes to nucleophilic acyl substitution?

1) Saponification of triglycerides

2) The process of transesterification

3) Cleavage of anhydride

The first example is particularly significant since it links several MCAT concepts. The breakdown of triglycerides into the glycerol backbone and fatty acids is known as triglyceride saponification, and it follows the same principles as nucleophilic acyl substitution. The R group is the glycerol backbone this time, the nucleophile is a strong base (like OH-), and the leaving group is a fatty acid!

Check the passages first if you don’t understand something

On first reading, passage-based questions are frequently unreliable. That example, you may be asked to define or supply a formula for something wholly unrelated to the core chemical concepts and knowledge base provided in the article’s categories.

If that’s the case, don’t panic if you don’t know the chemical formula for Brochantite—in nearly all cases, that information will have been given, though briefly, in the chapter to which the question is linked.

If a question linked to one looks completely out of the blue, or if it appears to be asking for information outside the purview of beginning chemistry/etc., it’s practically a certainty that your answer is right there in plain sight only a few inches away. Reread the text carefully and concentrate on finding the solution in the information supplied.

Except when the question includes chemistry, the MCAT isn’t about memory

The truth of the MCAT’s CPBS portion is that you’ll need to memorize quite a few facts, but they’re all interconnected in some manner. Numerical and nomenclatural prefixes and suffixes, for example, are critical—being able to describe the difference between chlorite and chloride compounds in clear English will save time.

When studying for the MCAT, memorization isn’t the be-all and end-all [RN1], but it is an important aspect of constructing the toolbox needed to correctly interpret the language employed in a chemical question.

Even though you’ll have access to a periodic table during the exam, learning as much of it as possible will be beneficial. The pop-up table on your testing screen should be used to corroborate your intuition or hypothesis rather than as a cheat sheet.

Even if you have trouble memorizing, this is significant since the time spent switching back and forth between the table and the exam may mount up quickly if you do so frequently.

Furthermore, the table supplied, like other periodic tables, does not provide full names of elements or vertical/horizontal trends, so you’ll have to figure out a lot of information on your own.

There’s a lot more chemistry and physics to remember for the CPBS part, but starting with these fundamentals, as well as common strong acids, strong bases, and polyatomic ions, will help you structure the more complex laws and equations you’ll need to remember come exam day.

Practice converting units

Having to physically compute unit conversions is one of the most time-consuming aspects of the CPBS section. Regular, if not daily, practice in multiplication and dividing by negative exponents, as well as studying how to convert the results of these calculations into many other units, should be included in your studies. This will help you save time and get accurate results quickly.

Simple questions should come first, then go back for passages

Discrete questions, or short one-off questions with four possible responses, should be rather straightforward by the time your exam day arrives. Because of the MCAT’s extensive knowledge base, these questions will frequently only need memorization of a fact or a basic computation.

Getting these simple-format questions out of the way before moving on to the more involved multiple-question passages will not only help you maximize the amount of time you have to read and analyze the passage’s text, but it will also likely boost your confidence for the more uncertain, even alien terrain that comes with it.

Half of your confidence boost will depend on having your hypotheses verified at least most of the time—that is, whenever you approach a discrete question, take a moment to formulate a broad hypothesis about the proper answer after carefully reading the question. This will allow you to eliminate answers that are clearly erroneous more quickly, giving you more time to choose amongst the likely correct responses.

A complete list of MCAT chemistry concepts

The MCAT is organized by the AAMC on ten Foundational Concepts that are spread over the four sections of the exam. Two of these fundamental principles are the focus of the Chemical and Physical Foundations of Biological Systems section.

It’s vital to notice right away that these core principles are articulated in somewhat extensive terms, so you’ll need to be able to both grasp and paraphrase them as provided by the AAMC.

The MCAT typically covers the range of subjects and concepts covered is extensive, but the depth to which any question will go is always restricted. The main majority of chemistry information examined on the MCAT will come from introductory and general chemistry, as well as first-year organic and biochemistry, as seen in the tables above.

Advanced molecular spectroscopy is not required, but you must be highly familiar with the fundamentals of mass spectroscopy. Let’s dive—or rather, wade—into the shallow but large pool of Foundational Concepts 4 and 5 for a complete overview of the MCAT chemistry subjects you’ll need to know.

Foundational Concept 4 

Complex organisms, such as the human body, employ physical principles to move materials, perceive and interpret ambient data and internal signals, and adapt to changes. These intra-organism processes may be described and quantified using equations and behavioral models because they function according to physical rules.

“The concepts of electromagnetic radiation, and their interactions with matter, can be utilized to create structural information about molecules or to take pictures of the human body,” according to the AAMC definition.

As a result, atomic structures may be used to forecast or simulate the physical and chemical characteristics of atoms, which could include calculating processes like ionization based on electromagnetic radiation in this case.

This may sound like a lot, but comprehending the nature of the CPBS section requires a grasp of the fundamental connections between physics and chemistry. There will be a few discrete questions that require you to simply calculate things like molar mass, but passage-based issues will require you to comprehend the synergistic nature of physical and chemical rules in order to choose your strategy to respond.

The diagnosis and treatment of frequently complex/systemic disease pathologies are shaped by this foundational understanding. As a result, difficulties relating to the physiological activities of the neurological, cardiovascular, and respiratory systems in human health will frequently appear in this area.

Foundational Concept 5 

The concept of FC5 is how the micro influences the macro. The scientific knowledge of “molecular dynamics of biological systems” is based on chemical concepts at the atomic and subatomic levels.

Furthermore, understanding the function of chemical processes in the formation of diverse frameworks, such as thermodynamics, intermolecular interactions, molecular dynamics and reactivity, and, of course, molecular structure, will be required.

The MCAT will require students to apply these key ideas to questions about molecular and cellular activities in human health and illness。

This fundamental concept’s categories make up the core pillar of chemistry knowledge assessed on the MCAT, accounting for the majority of questions in the CPBS segment.

Make a note of their appearance in any study resources you have so far when examining these areas. Although much of it is general chemistry, so you should be familiar with it, some of the biochemistry-focused subcategories may require more specialist study resources to compensate for any gaps in your earlier training.

FAQ

How much organic chemistry is on the MCAT?

You probably spent a semester or two studying organic chemistry, yet the MCAT will only ask you roughly 6 to 12 questions on it out of 230 total questions. In other words, organic chemistry is expected to account for only 3 to 5% of your overall test.

What types of MCAT chemistry questions?

Broad chemistry, biochemistry, and organic chemistry are the three general categories of chemistry knowledge assessed on the MCAT. There are many subtopics within those broad categories, but the great majority of chemistry questions will draw from general and biochemistry, so making sure you understand the fundamentals of these subjects will be crucial as you study.

How can I quicken my passage-based questions?

Surprisingly, parts of the CARS technique can be really useful in this respect, especially with chemical sections. For any passage-based inquiry, active reading is critical—you should be able to approach a text with queries like “what is the theme of this passage?” in mind, as well as summarise longer phrases for better understanding.

Reading difficult material during exam preparation will also enhance and speed up your analytical abilities, even on scientific parts. In general, the better you are at reading and thinking while reading, the better you will do on exam day with all passage-based questions.

Are difficulty practice questions and tests better?

Both yes and no. There’s a place for really difficult practice questions and topic exams, but for diagnostic reasons, it’s always better to choose to practice exams that closely resemble the actual MCAT.

You want an accurate assessment of your ability at the start and halfway through the test, therefore attempting material that is meant to be more difficult than the actual exam will certainly lead to disappointment.

Include deliberately tough computations and passages in your study sessions, but do so in moderation. After all, you’re taking the MCAT, not the USMLE Step-2.

How do I study for the organic chemistry part?

Simply said, you’ll require additional time. The good news is that because the MCAT is “a mile wide and an inch deep,” you may concentrate on building a broad base of basic or fundamental knowledge rather than becoming overly specific about any one component of organic chemistry.

If you have the time, take a summer course in whatever prerequisites you haven’t finished, but if you don’t, you may always look for the textbooks from these classes and go through them thoroughly.

In this instance, however, hiring an MCAT instructor or prep service will be the most effective and time-saving alternative, since they will be able to create a study schedule that is tailored to your individual needs.

Conclusion

So, how much chemistry is on the MCAT? Chemistry accounts for almost 70% of CPBS questions, with general and organic chemistry contributing to 10% of BBLS questions.

This article included all of the necessary information as well as practice strategies for MCAT chemistry questions.

Remember that you’ll need to devote a significant amount of time to studying for the MCAT and that we’ll be here to help you along the way! We’ve got your back, and you’ve got this!

How Much Biochemistry Is On The MCAT?

How much biochemistry is on the MCAT? In this post, we will provide you with the answer to this question as well as some useful tips to study biochemistry.

June 17, 2022

You’ve finished your premed course prerequisites and are now prepared to take the MCAT. You may have a lot of questions: How difficult is the MCAT? What topics will be addressed in the test? How much biochemistry is on the MCAT?

Unlike organic and physical chemistry, the MCAT will include a lot of biochemistry. Surprisingly, the amount of time you spend in college studying a topic has little bearing on how much it will appear on the test. Even if you spend many sleepless hours agonizing about organic chemistry mechanisms or difficult physics issues, understanding such courses would not get you as many points on exam day as knowing biology.

So what should you do? If you’re in a mess, read on our page!

This page contains all of the information you’ll need for the MCAT biochemistry section. We also provide study tactics developed by experts who got a perfect 132 on the C/P and B/B sections, which you can apply to improve your MCAT score. Let’s get going!

how much biochemistry is on the mcat

What percentage of the MCAT is made up of biochemistry?

Biochemistry makes up around 25% of the MCAT, with between 25 and 35 questions covering the subject in each of the four sections: Chemistry and Physics (C/P) and Biology and Biochemistry (B/B).

Here are the MCAT biochemistry topics you should be familiar with:

  • Proteins
  • Nonenzymatic protein function 
  • Enzymes
  • DNA
  • RNA 
  • Carbohydrates
  • Lipids and membranes
  • Carbohydrate metabolism
  • Lipid and amino acid metabolism 
  • Biochemistry lab techniques

How can you prepare for the MCAT Biochemistry?

You might begin by learning about the MCAT Biochemistry in order to achieve a high score. You may design the fullest good study plan this way.

Visit the Association of American Medical Colleges website to learn more about the MCAT biochemistry section in particular. This webpage provides an overview of the topics included in the MCAT’s biology and chemistry sections.

Because a solid MCAT score will increase your chances of being accepted into the medical school of your choice, you should start studying as soon as possible; many experts recommend starting at least three months before the exam.

In general, dedicating a large amount of time each day to studying can assist you in being well prepared. Starting early can help you cover all of the subjects you’ll need for the test while also avoiding clutter. Cramming won’t help you score well on the MCAT in most situations.

You might also want to get a copy of the Official MCAT Exam Guide, which is available on the Association of American Medical Colleges’ website. This guide contains topics and questions that are comparable to those found on the MCAT.

It also contains thorough explanations of why the answers are correct or incorrect, as well as answers to the sample questions. The guide also contains advice on how to correctly answer the questions and how a high MCAT score affects admittance into medical school.

Practice examinations that you may take at home can be beneficial to you. Practice examinations are available on the website of the Association of American Medical Colleges, as well as on other preparing websites and in other study manuals.

You can also get practice exams and commentary if you attend an MCAT Biochemistry Prep course.

Biochemistry study tips

Biochemistry is a crucial topic for students studying medicine, nursing, and pharmacy.

Many people will find studying this topic challenging and complicated. So, based on my personal experience, here are some tips on how to learn biochemistry.

#Tip 1: Know the concepts

Biochemistry, as we all know, is a scientific discipline. As a result, you must comprehend its notions.

In biochemistry, aspects of carbohydrates, proteins, lipids, and nucleic acids are explored.

As a result, you must comprehend its function, generation, metabolism, and excretion in and by the body. This helps you recall things and write effectively on examinations.

Understanding the need also allows you to consider its applicability in practice.

Glucose metabolism, glycogen synthesis, lipid synthesis, protein synthesis, nucleic acid synthesis, and other general concepts are covered.

#Tip 2: Know the scope and depth of biochemistry

From microbes to larger plants and animals, biochemistry has a broad reach.

Biomolecules including enzymes, carbohydrates, toxins, and electrolytes use its principles.

Knowing the true scope and complexity of biochemistry can assist you to determine the scope of the topics you’ll need to study.

#Tip 3: Using the TAID P technique, practice understanding graphs, figures, and tables

Title, axes, independent variable, dependent variable, and patterns are all abbreviated as TAID P. You will be able to grasp what the data is saying if you can recognize these elements in a graph, figure, or table.

Let’s look at an example that uses the TAID P method:

T (title): The title claims that medicine has an influence on cell survival. We may deduce from the title that the researchers are administering medication to cells and monitoring their survival.

A (axes): The x-axis represents rising medication micromolar concentrations, while the y-axis represents the percentage reaction. What exactly does a % answer imply? We know it has to do with survival based on the information we’ve gathered thus far.

I/D (independent/dependent variables): The axes make determining the independent and dependent variables, which in the TAID P approach are I and D, simple. What are the independent and dependent variables, for starters? The independent variable is anything you intentionally modify. A measured reaction based on this change is the dependent variable.

What is the independent variable in our figure? The independent variable is always represented on the x-axis. The concentration of drugs! The dependent variable, on the other hand, is shown on the y-axis, so we know its drug response.

P (patterns): Finally, let’s look at the patterns in our graph to see if there are any large-scale trends. What do you think of our graph? Is there a medication concentration at which the percentage response increases dramatically? Between 7 and 8 uM, a dramatic switch in response levels occurs, and medication doses over 8 uM result in a positive % response.

Within 15-20 seconds, you should be able to recognize the TAID P components for any given figure. The goal is to grasp the overall picture without being bogged down in the specifics. If you find yourself thinking for more than 15-20 seconds, finish your idea and go on to the next section of the chapter or the questions.

During your initial reading of the chapter, don’t spend too much time on any one figure because there may not even be a question on that figure! For example, if an MCAT biology/biochemistry passage has Figures 1, 2, and 3, the test writers may only offer a question on Figures 1 and 2. You don’t want to waste time learning Figure 3 in-depth if the MCAT will not ask you a question about it.

#Tip 4: When reviewing a biochemistry figure while going over your errors, pay close attention to every minute detail

When taking an MCAT biochemistry passage with a figure, you should return after submitting your answers and properly rereading the text. Why are you doing this? You will improve your ability to understand figures fast and accurately by exercising with the TAID P approach with no time limits.

You will have taken dozens of MCAT biochemistry sections by the time you have completed multiple full-length practice examinations. There are very few MCAT statistics that will confuse you if you take the time to examine each of them in detail throughout your test review.

#Tip 5: All twenty amino acids have a one-letter code, a three-letter code, structures, and chemical characteristics

This is one of the most high-yield recommendations you’ll get because amino acid questions will almost certainly appear on both the MCAT C/P and B/B sections. It is not enough to recall the structures of the twenty amino acids; you must also understand the characteristics that each structure provides.

Would you rather see an arginine, which has a positive charge, or a valine, which has a hydrophobic charge, on the outside of a protein? Because a protein’s exterior is frequently made up of hydrophilic residues that interact with water, the charged arginine, which is positively charged and can interact with water, is much more likely to be found there.

Let’s take a look at an MCAT-style question on amino acids:

In a protein domain, which of the following amino acids is most likely to be found at the intersection of two alpha-helices?

  1. a) Proline
  2. b) Tryptophan
  3. c) Serine
  4. d) Glutamine

Proline and glycine are two amino acids that are known to add flexibility and kinks to peptide strands. Because an amino acid that introduces flexibility at the junction of two alpha-helices is likely to shift the chain’s orientation, answer choice A is accurate.

The question did not ask us to identify the structure of proline; rather, it asked us to determine which amino acid side chain possesses the required qualities to be found at the intersection of two alpha-helices. Know your amino acids inside and out to score easy (and necessary) points on the MCAT!

how much biochemistry is on the mcat

#Tip 6: Focus on rate-limiting stages and big picture notions to grasp the integration of metabolism

Many students believe that in metabolic pathways like glycolysis, they would need to learn every enzyme, reactant, product, and structure. Memorizing and remembering these facts is a difficult task that will take time and effort. Your time and effort, on the other hand, are quite important while preparing for the MCAT, and they are far better spent on high-yield content that is more likely to appear on Test Day.

What is glycolysis’ high yield? Rather of remembering every little detail, focus on the rate-limiting enzymes that regulate route flux, or how quickly the process moves. In other words, for each metabolic pathway, you should be able to answer the following questions: what are non-reversible enzymes, and how does the body control these enzymes to regulate human metabolism?

Consider the following scenario. The rate-limiting step in glycolysis is phosphofructokinase-1 or PFK-1. This indicates that the glycolysis pathway can only move at the same rate as PFK-1. Why would the body do something like this? Within metabolism and biological processes in general, rate-limiting phases are frequently critical regulatory points.

If we consume a huge meal and have a lot of glucose in our blood, we want to metabolize it so that we may use it right away or store it for later. As a result, we must engage in glycolysis. Insulin is released into our circulation when we consume a substantial meal, and it upregulates PFK-1 in a sequence of stages, causing the enzyme to operate faster and allowing glycolysis to proceed more quickly.

At this level of detail, you should be aware of the following metabolic pathways:

  • glycolysis
  • gluconeogenesis
  • glycogenesis
  • glycogenolysis
  • Krebs cycle
  • electron transport chain/ATP synthesis
  • fermentation
  • pentose phosphate pathway
  • fatty acid synthesis
  • fatty acid oxidation (beta-oxidation)

Tip #7: Learn how to use experimental techniques

PCR, Western blot, Southern blot, Northern blot, gel electrophoresis, SDS-PAGE/reducing gels vs native gels, molecular cloning, and transformation/conjugation/transduction are examples of biochemical experimental procedures used on the MCAT.

These tactics will appear in biochemistry passages, and you will be able to work your way through them by using strategies 1 and 2. We’ll go through the high-level functions of each approach here.

  • PCR: This technology amplifies tiny quantities of DNA and is used in current applications like sequencing and detecting cellular mRNA levels.
  • Western blot: This technique uses antibodies to quantify protein levels in a sample.
  • Southern blot: This method determines the amount of DNA present.
  • Northern blot: This method is used to measure RNA levels.
  • Gel electrophoresis is a technique for sorting molecules by size.
  • SDS-PAGE/reducing gels: This approach uses size to separate denatured proteins.
  • Native gels: This method separates proteins in their natural shape, preserving subunit integrity.
  • Molecular cloning: a process for inserting genetic information into a plasmid for the purposes of protein production or genetic modification.
  • Transformation, conjugation, and transduction: the ways for transferring genetic information into bacteria.

You’ll be acing all of the MCAT biochemistry questions in no time if you use these 7 study tactics!

How Long Study For MCAT And When Should You Start?

When students decide to pursue a career in medicine, the next question is when to begin and how long study for MCAT. This post will help you figure them out.

June 17, 2022

You’ll need to start thinking about taking the MCAT after you’ve decided to go to medical school. Many people are concerned about the problem: “How long study for MCAT?”

This is a crucial issue to be addressed because if you don’t prepare ahead of time and give yourself adequate time to study, you might find yourself repeating the process for years.

You should really consider it, and this advice will assist you in doing so. This post not only discusses how much time you should spend studying for the MCAT but also gives a timeframe for when you should begin preparing so that you may submit your medical school applications on time.

how long study for MCAT

Do you get ready for the MCAT?

So, you’ve made the decision to go to medical school. Congratulations on making your choice! However, choosing this path of additional study is more complicated than just requesting admission to your desired medical school. Instead, you’ll have to work hard to get accepted, which involves producing confirmation of a passing MCAT score.

In a nutshell, the MCAT (Medical College Admission Test) is a standardized exam that assesses your academic and practical understanding of a variety of medically important science disciplines. It is widely regarded as one of the most difficult admissions-style tests available. As a result, many aspiring medical students wonder “how long do people study for the MCAT before taking the test”.

For a variety of reasons, this might be a difficult topic to answer. Nonetheless, this advice should assist you in better preparing for the MCAT by outlining how much time you should devote to studying and when you should begin. Overall, this tutorial should help you get started on building an MCAT study guide that suits your learning style.

How long study for MCAT?

This could be one of the most pressing concerns you have now that you know you’ll have to take the MCAT soon. That’s only fair because the response will likely influence when you schedule your exam, as well as any other commitments you make in the weeks leading up to the big day.

However, the solution may not be as satisfactory as you had hoped. That’s because the amount of time you’ll need to prepare for the MCAT is entirely dependent on you. Your preparation duration will be determined by your understanding of the required information as well as your readiness to take a lengthy, high-stakes test. Even your current level of commitment to your career and schooling might affect the amount of time you have to prepare.

However, previous MCAT test takers have shared information on “how long did you study for the MCAT”. On average, prospective medical students report they spend 3 to 6 months really preparing for the exam. This includes things like studying information, taking practice examinations, and enrolling in preparation classes. Some people have even completed all of this in a single month, albeit these exam takers aren’t often students who are already enrolled in classes.

So, how long should you study for MCAT?  Because each student is different, keep the following considerations in mind when determining how much time you’ll need:

You’ll require more time the more non-MCAT obligations you have. Some premed students set aside a summer, often following their junior year, to focus only on MCAT preparation.

2.5 to 3 months is generally enough time for those kids to be totally prepared. Many other premeds, on the other hand, must mix employment or college education with their study, which necessitates more time.

Many students may work full-time throughout their MCAT preparation and still do well, but if this is you, consider dedicating 4 to 5 months instead of 2-to 3.

It is recommended that you take at least five full-length tests. The MCAT takes 6 hours and 15 minutes to complete, not including breaks. Because you’ll want to prepare under test-like settings, each practice test will take nearly a full day to complete.

If you just have a few “empty” days in your personal calendar, you may need to lengthen your deadline or rearrange your obligations. The word “at least 5 “ is ideal here, but it depends on your circumstances, just like any other part of MCAT practice. It is far more vital to thoroughly review each practice exam than it is to cram as many examinations as possible.

Your timeline should be determined by your objectives and knowledge of the content. One point worth mentioning is the student’s familiarity with MCAT scientific content. Don’t worry if you’re a touch rusty on the content; most students don’t recall the ins and outs of acid-base chemistry or projectile motion from undergrad! The more knowledge you need to re-learn, however, the longer you should plan to prepare. Any content review should be added to at least 1.5 months of “strategy only” preparation (practice passages, full-length tests, review, etc.).

You don’t have to study for 8 to 12 hours every day. Here’s something a little more uplifting!  This is not only unneeded, but it may also lead to fatigue and irritation when life’s events unavoidably interfere. 

On a typical MCAT day, students are advised to study for 4-6 hours, with the apparent exception of practice exam days. If you manage your time well and continuously examine your deficiencies, you’ll discover that you have more than enough time to develop without having to put your entire life on wait.

Preparing for 4 months at 4 hours per day is often preferable to 2 months at 8 hours per day. Also, take vacations – your performance will improve!

How many hours to prepare for the MCAT in total?

how long study for MCAT

You should start focusing on your MCAT preparation on a smaller scale now that you have a basic notion of how long it will take you to prepare. To put it another way, you should start thinking about how many hours you’ll need to study for the MCAT overall and on a daily basis.

Again, your options may differ based on a number of extenuating factors. First, you might not spend the same amount of time preparing for each subject on the MCAT. When it comes to allocating study hours, if you feel more skilled in one topic than another (based on practice examinations), you may opt to prioritize your weaker areas.

Second, the number of hours you can devote to studying on a daily, weekly, or even monthly basis may be determined by your life and commitments leading up to test day. While these commitments may limit your study time, it is critical that you arrange at least some study time each day. That way, you’ll be able to stay focused and on pace for a solid showing on test day.

With this in mind, many aspiring MCAT takers find it beneficial to set aside 1-2 hours each day for studying throughout their preparation time. You could also find it helpful to set that study time every day so that other obligations don’t interfere.

 

When you extend that program to a 3-6 month preparation period, you’ll realize that you’ll need to spend 200-300 hours studying for the MCAT. At first look, that may appear to be a lot, and it is. The MCAT is a difficult exam that tests not just the academic material but also critical thinking abilities. As a result, people who want to succeed must be ready to make a deliberate effort to fully prepare.

When should you begin preparing for the MCAT?

As previously said, one of the keys to success on the MCAT is preparation. So it’s only natural to wonder when such critical preparations should begin. Some people may believe that they should begin learning as soon as feasible. However, many potential exam takers are concerned about burnout while studying. As a result, limiting the majority of your studying to a specified pre-test time makes sense.

Of course, you won’t know how long your test period will be until you choose a date. After that, you may start working backward to figure out an informal “start date” for your MCAT study regimen. As previously stated, many test takers who sign up for a far-off exam date study for a full six months. Those with greater responsibilities, on the other hand, may choose a 3-month study time.

However, longer isn’t necessarily better. Some medical students claim that with only 1-2 months of focused preparation, they were able to pass the MCAT. In any event, when it comes to planning your MCAT study schedule, your past academic experiences should serve as a starting point.

Conclusion

You should have a clear grasp of “how long to study for MCAT” by now. If you’re still having trouble figuring out a study schedule that works for you, start by calculating how long you believe you’ll need to study. After that, you may start constructing a daily study schedule to keep you focused on your objective — a passing MCAT score.

Don’t forget to take our free MCAT practice test at Medtutor to get familiarized with the format as well as the questions of the actual exam to strengthen your knowledge and skills, as a result, enhancing your chance to pass the MCAT exam with a high score on your first attempt. Good luck to you!

What Are the Difference Between MCAT Vs GRE?

There are some differences between the MCAT vs GRE. Continue reading to discover more about these crucial standardized entry examinations and how they differ.

June 16, 2022

Considering medical school? You then have an option, unlike most pupils. You can choose between the MCAT vs GRE. The GRE and MCAT are two graduate school entrance examinations for medical, dental, and other professional courses.

Choosing the right standardized test for your graduate studies and future employment is a significant step. Knowing the differences between the GRE and the MCAT can assist you in making an educated selection.

You may find it difficult to get accurate information on the internet, therefore we have included the greatest and most up-to-date information about GRE VS MCAT in the following post.

mcat vs gre

What are MCAT and GRE?

The GRE is more generally acknowledged and is used for admission to a wide range of graduate schools, whereas the MCAT is only used for medical school entrance. Certain medical schools, such as those in veterinary medicine, may accept either the GRE or the MCAT from candidates.

What is GRE?

The GRE, or Graduate Record Examinations, is a more general standardized examination that is accepted for a wide range of masters and doctoral programs in the United States and Canada. The Educational Testing Service writes and administers the GRE General Test (ETS). The exam assesses students’ ability to reason verbally, quantitatively, and analytically.

According to statistics, over 700,000 students take the test each year, and while it is computer-based, paper-based assessments are provided in places where computers are unavailable.

What is MCAT?

The MCAT is the “gold standard” for admission to practically all medical schools in Canada and the United States. The Association of American Medical Colleges (AAMC) created the MCAT to assess candidates’ understanding of biological and social sciences, as well as analytical thinking, reading comprehension, and problem-solving abilities.

According to research, over 85,000 students take the MCAT each year, and you must take it as part of the application process if you want to enter a medical school in the United States or Canada.

Although the GRE and MCAT cover many of the same topics, there are some significant variances. We’ll go through the essential components and aspects of each test in the next paragraphs.

What are the similarities between MCAT and GRE?

Both tests are standardized. This implies that all test takers get the same set of questions. The same standards are used to assess their responses.

Both are used as entrance tests by committees to choose which candidates should be admitted to graduate school.

Finally, both tests are computer-based. They, like the GMAT, will be given by a computer system and tailored to your ability.

MCAT vs GRE: The overview of the comparison

The following are the key differences between the MCAT and the GRE:

  • The MCAT is for students applying to medical school, but the GRE is more generic and recognized by graduate and professional institutions all around the world.
  • The MCAT has four sections that assess health-related abilities, whereas the GRE has three sections that assess basic math, writing, and reasoning skills.
  • The MCAT is offered 25 times a year, mostly in the United States and Canada, but the GRE is offered continuously and has a wider worldwide reach.
  • Students can choose to put in only their top GRE results, but prospective universities can see every MCAT score ever obtained.

Below is a side-by-side comparison table to help you understand how each test is structured:

What are the differences between MCAT and GRE?

#1 MCAT vs GRE: What contents do they cover?

MCAT

The MCAT is a test that assesses prospective candidates on the abilities and knowledge needed for success in medical school. The test content is created and updated jointly by medical educators, practicing physicians, and other medical students.

The test is broken into four parts in general. Each part is regarded as a precondition as well as a predictor of a student’s future performance. Let’s take a deeper look at each component one by one.

  • Biological and Biochemical Foundations of Living Systems

Students will complete questions in this area to demonstrate their understanding of biological and biochemical topics. They’ll also have to demonstrate how they approach scientific inquiry and scientific thinking.

Biological and Biochemical Foundations of Living Systems has 59 questions on the MCAT, including passage-based and discrete questions. This course will take 95 minutes to complete, and students will have access to the periodic table throughout.

  • Chemical and Physical Foundations of Biological Systems

Students will demonstrate their understanding of basic chemical and physical basis ideas in this part. This necessitates them to answer questions that assess their knowledge of the functions of human organs, tissues, and organ systems.

Section 2 has 59 passage-based and discrete questions, much like Section 1. Students will have 95 minutes to finish it and will be allowed to use the periodic table for guidance.

  • Psychological, Social, and Biological Foundations of Behavior

This section contains health-related tasks that are more concerned with human and social concerns than with scientific issues. There are also 59 passage-based and isolated questions in Section 3. It will take students 95 minutes to finish.

  • Critical Analysis and Reasoning Skills

This part follows the format of many verbal reasoning tests. It’s intended to assess a student’s critical thinking and reading comprehension abilities, particularly in relation to medical information.

Each section will be between 500 and 600 words long but will be somewhat difficult. There will be a total of 53 test questions.

GRE

The GRE General Test will be taken by the majority of entering graduate students. This is a fundamental, all-encompassing test that covers a wide range of topics. GRE Subject Tests are also available.

There are three sorts of questions on the GRE General Test. Here’s a deeper look at each segment and what students may expect.

  • Verbal Reasoning

The GRE General Test’s Verbal Reasoning section assesses a student’s ability to make inferences and interpret meaning from a range of text types. The questions will be divided into two halves. Reading texts and completing the questions that follow will make up one portion. In the other portion, students must read texts and accurately understand them.

Each part will have 20 questions and a time limit of 30 minutes.

  • Analytical Writing

The Analytical Writing section of the GRE General Test demands students to use the written word to explain and articulate themselves. There are two components to this test. Students will have 30 minutes in Section 1 to study a topic of general interest. Students will have 30 minutes in Section 2 to examine an argument.

mcat vs gre

  • Quantitative Reasoning

Students will demonstrate their ability to grasp and evaluate diverse forms of quantitative data in the Quantitative Reasoning section of the GRE General Test.

For this section, students will use an on-screen calculator. The questions are separated into two sections. Students have 35 minutes to complete each of the 20 questions in each session.

  • GRE Subject Tests

In addition to the GRE General Test, students can take GRE Subject Tests through the ETS. Though this test isn’t normally necessary for graduate school admission, it might help students stand out in a particular field of study.

These tests are paper-based and only available at specific testing locations. Subject tests for the GRE are available in the following areas:

  • Biology
  • Chemistry
  • Literature in English
  • Physics
  • Psychology
  • Mathematics

The Biology and English Literature Subject Tests will be phased out after April 2021.

#2 MCAT vs GRE: What are the timeframes for both exams?

MCAT: Testing timelines

The MCAT is often taken in the calendar year before the year in which the student intends to enroll in medical school.

Between late January and early September, the AAMC administers the test around 25 times. There are hundreds of testing sites around the United States and Canada, as well as a few international locations.

Testing limits

The AAMC has set testing limitations to limit how many times a student can take the MCAT in a calendar year. The following limitations are in effect:

  • In a calendar year: 3 times
  • Over a two-year period: 4 times
  • Lifetime: 7 times

Medical schools will have access to a student’s whole academic record, emphasizing the need for early preparation.

Length of test

The MCAT exam is scheduled to last 6 hours and 30 minutes, excluding breaks and setup time. The duration of the show is around 7 hours and 33 minutes.

GRE: Testing timelines

The GRE General Test can be taken on a computer at any time during the year. It’s offered at more than 1,000 Prometric testing facilities in more than 160 countries across the world. Testing is done on a regular basis at practically every site. The GRE General Test is only offered three times each month in various parts of China and Korea.

There is an at-home option for students who reside in a distant area where the computer-based test is not necessary. This exam is similar to the one administered at a testing facility and is administered under the supervision of a human proctor.

Testing limits

Every 21 days, students can repeat the GRE General Test. This can happen up to five times in a calendar year. GRE Subject Tests, on the other hand, are only given three times a year, in:

  • April
  • September
  • October

If students are obliged to take the GRE on paper, only October, November, and February are available.

Length of test

The GRE General Test takes around three hours and 45 minutes to complete. However, small breaks will be included, perhaps lengthening the overall sitting duration.

Each GRE Subject Test takes two hours and 50 minutes to complete.

#3 MCAT vs GRE: What are their scoring systems?

MCAT: Scoring 

The MCAT exam yields five different results. Each of the four areas described above has a score, as well as a thorough overall score.

On a scale of 118 to 132, each of the four sections is evaluated. The AAMC then adds these scores together to give a total score. This might be anything from 472 and 528. Around 30 days following the exam, students should expect to get their results.

GRE: Scoring

Three different scores are available on the GRE General Exam. On a scale of 130 to 170, with 1-point increments, the Verbal Reasoning part is graded. The Analytical Writing component is graded on a half-point scale from 0 to 6. The Quantitative Reasoning part is graded in 1-point increments in a range of 130 to 170.

On a scale of 200 to 900, with 10-point increments, each GRE Subject Test is graded. Admissions officers can examine every score a student achieves when they take the MCAT. However, the ETS created a ScoreSelect option that lets students provide only the scores they want.

Students will receive four score reports for free with each test, which they may send to any academic institution that accepts them. They can provide scores from that day’s test or from scores they’ve received in the previous five years.

#4 MCAT vs GRE: How do they cost?

MCAT Fees

The MCAT costs $320 if students schedule their exams in advance. If students wait until eight days before the exam to register, the price increases to $375. Depending on their location, some test takers may be charged an extra $115 registration cost.

GRE Fees

The GRE General Test costs vary depending on where you take it. It costs $205 in most parts of the world. The following exceptions, however, apply:

  • China: $231.30
  • Australia: $230
  • India: $213
  • Turkey: $255
  • Nigeria: $226

GRE Subject Tests cost $150 globally.

mcat vs gre

Which should you take: MCAT or GRE?

The MCAT is typically considered the more challenging of the two examinations, compared to the GRE. It’s a lot lengthier and more content-focused than the GRE, which is more concerned about broad ability in specific areas.

Many pre-med students estimate that studying for the MCAT takes 300-350 hours. However, the GRE may be more challenging for you if you lack writing or critical reading skills, are a non-native English speaker or have a restricted vocabulary.

Whether you should take the GRE or the MCAT depends on where you want to go to school and what you want to do with your life. The GRE is more generally acknowledged and is used for admission to a wide range of graduate schools, whereas the MCAT is only used for medical school entrance.

If you’re not sure if you want to go to medical school yet, it could be worth it to take the GRE first and put off studying for the MCAT. GRE results are valid for five years, however MCAT scores are only valid for three years.

As a result, you might take the GRE first and then decide whether or not to take the MCAT. If you eventually want to go into a healthcare-related area, such as public health, rather than go straight to medical school, this might be an excellent option.

Another thing to think about is your future career. Certain medical schools, such as those in veterinary medicine, may accept either the GRE or the MCAT from candidates. If you struggle with critical reading or writing, the GRE may be a better option, as it is both less expensive and shorter.

How to prepare for MCAT and GRE

Both examinations will need you to improve your reading comprehension abilities, but the subject they cover is vastly different.

Biology, Organic Chemistry, Chemistry, Physics, Psychology,  Maths, Biochemistry, and Sociology, will all be tested on the MCAT. Although you won’t be required to remember all you studied in those classes, the MCAT will expect you to know and apply ideas and information from all of those subject areas. The AAMC advises that a pre-med student spends between 300 and 350 hours studying for the MCAT across several months.

You’ll need to examine core ideas and grasp strategic approaches to each type of question on the GRE while studying. The average person studies for the GRE for one to three months.

Spend some time determining your score goals before you begin studying for any exam. Above all, base your score targets on the criteria of your desired graduate schools. Take some time to investigate the scoring criteria for your programs of interest. Create a study plan and calendar once you’ve decided on the schools to which you’ll apply and set your score targets.

MCAT vs GRE: FAQ

Which is easier, the MCAT or the GRE?

The GRE is frequently regarded to be more straightforward than the MCAT. This is due to the fact that it does not require expert knowledge in a certain subject and instead covers a wide range of less challenging issues. Other examinations, such as the LSAT and GMAT, are more demanding than the GRE.

Is the GRE required for medical schools?

Answer: Medical schools do not usually need entering candidates to take the GRE. Most medical school applicants must take the MCAT to be considered for admission.

Is the GRE more difficult to pass than the SAT or ACT?

Yes, you can. The GRE is considered by most test takers to be more challenging than other standardized examinations such as the SAT or ACT. This is true despite the fact that the GRE’s math section is widely thought to be simpler than either of those two examinations.

What is a poor GRE or MCAT score?

Answer: A “poor” GRE or MCAT score is one that falls below the program’s entrance requirements. However, the poorest 10% of GRE test takers score less than 139 in the verbal portion and less than 141 in the quantitative component. The worst 10% of MCAT test takers have a score of 488 to 491.

What are good MCAT and GRE scores?

A decent MCAT score for all four parts is 508 points[3].

Because the GRE is divided into three sections, you’ll receive three unique scores. Here are some examples of good GRE scores:

  • 4.0 in the writing section
  • 155 in the spoken department
  • 156 in the quantitative section

Conclusion

You should be able to determine which admission exam is necessary for your next steps now that we’ve gone through the MCAT and GRE debate in greater depth. The major difference between the MCAT vs GRE examinations is the main goal.

The school you want to attend and the job path you want to follow determine which exam you should take. Take the MCAT if you’re solely applying to medical school. It demonstrates to the software that you possess appropriate knowledge and abilities.

The GRE can accomplish the same goal, but it is more generic. The analytical writing and speaking parts are two sections that aren’t very applicable to medical school.

We hope this post was helpful in answering your question.

Don’t forget to take our free MCAT practice test at Medtutor to get familiarized with the format as well as the questions of the actual exam to strengthen your knowledge and skills, as a result, enhancing your chance to pass the MCAT exam with a high score on your first attempt. Good luck to you!

How To Ace The MCAT Physics Equations?

MCAT Physics Equations is one of the most necessary parts of the MCAT exam. Follow this article to find out how to ace this test portion.

June 16, 2022

For the purpose of getting and achieving a high MCAT physics equations performance, would you have to be familiar with a certain set of linear equations? The MCAT’s chemistry and physics part, or the physics and chemistry portion for short, may be difficult, specifically if you don’t study for it.

It is essential that you master a few physics equations before taking this portion of the MCAT. If you think about it, all of the actions that take place in organisms are guided by physical principles! Each physics equation you’ll really have to understand for the MCAT is covered here, along with some pointers about how to apply them well on examination day.

mcat physics equations

How Much of the MCAT is Devoted to Physics?

How much physics will there be on the MCAT, you ask? The first portion of the MCAT, Chemical and Physical Foundations of Biological Systems will test your proficiency in physics. The AAMC estimates that around a quarter of the primary data collection methods will be based on material from a beginning physics course.

How do we define the term “initial physics”? This portion of the MCAT will not require you to use extremely difficult physics equations, but you must be able to use physics principles from your 2 different entry-level undergraduate physics classes to show a comprehensive comprehension of the dynamics of biological systems. In addition to the passage-based physics questions, you may anticipate seeing several stand-alone discontinuous physics problems as well. After taking basic physics, it is a good idea to take a few practice tests to see how much of what you learned sticks.

Understanding how living creatures carry resources, detect their surroundings, analyze signals and react in terms of physical principles is an important part of the MCAT. 40% of the MCAT chemistry and physics part will concentrate on this fundamental principle and cover the following physics-related content:

  • 4A – Transverse movement in living organisms, forces and work, energy and equilibrium
  • 4B – A vital role in the circulatory system, oxygenation, and other metabolic processes
  • 4C –   Electrochemistry and the components of electrical circuits.
  • 4D – Light, noise, and matter interaction in four dimensions.
  • 4E – Atomic chemistry, nuclear decay, atomic electronic properties, and atom biochemical activity

Important Physics Equations MCAT

Many physics equations for MCAT may be found online, and which ones are essential for the MCAT? The AAMC advises that you understand the following physics equations in order of importance:

4A – Transverse movement in living organisms, forces and work, energy and equilibrium

Different forms of renewable energy and the processes by which they may be converted are the emphasis of this portion of the website.

  1. Newton’s Second Law: F = ma

An object’s net force (which is called F for short) is inversely proportional to its mass (or the m) and acceleration (or the a). This equation is Newton’s second law (a).

An object’s net force (which is called F for short) is inversely proportional to its mass (or the m) and acceleration (or the a). This equation is Newton’s second law (a).

  1. Work By a Constant Force: W = Fd cosθ

This equation illustrates the concept of work energy or the amount of work (W) a constant force (F) may accomplish on a moving object. When a force is applied to an item, it travels a distance equal to its cosine theta (cos), and this is the equation used to calculate the displacement.

  1. Work Kinetic Energy Theorem: Wnet = ΔKE

Work (Wnet) on a moving item, particle, or network is equal to the difference in angular momentum (KE) of such a particle moving together.

  1. Kinetic Energy: KE = ½ mv2

There are two forms of energy in movement: gravitational and kinetic. In this case, the energy is associated with a specific mass (m) and a specific velocity (v) (v). A particle’s kinetic energy is inversely related to its acceleration (v2).

  1. Potential Energy: PE = mgh

Gravitational potential energy (which is often called PE for short) is described by this equation, which is dependent on the location of an item. It’s important to know how much mass the item has (m), how fast the object is moving due to gravity (g), and the organism’s height in m in order to utilize this equation (h).

  1. Potential Energy: PE=½kx2

It’s important to know how much mass the item has (m), how fast the object is moving due to gravity (g), and the organism’s height in m in order to utilize this calculation (h). Potential Energy (PE) is defined as 12kx2 and has a value of 6. A spring, for example, exerts an elastic force when stretched or compressed. k is the spring constant, and x is the distance the spring is stretched in this potential energy (PE) equation. The stiffness of a spring is determined by its spring constant.

4B – A vital role in the circulatory system, oxygenation, and other metabolic processes

In this topic, we’ll discuss fluid dynamics and how they affect the respiratory and regulating systems.

  1. Pascal’s Law of Hydrostatic Pressure: P = ρgh

Static fluids are subject to this rule, which states that pressure increases with depth. Hydrostatic pressure increases the pressure in a fluid at a certain depth, and this pressure rises as depth decreases. Hydrostatic pressure (P), (liquid density), g (gravitational acceleration), and h (liquid depth/height) are the variables in this equation.

  1. Continuity Equation: A∙v = constant

Fluids are defined by their ability to flow indefinitely. Continuity of flow is ensured by the conservation of mass in a fluid system. A represents the flow’s cross-sectional area, and v is its velocity in this equation. A fluid system’s velocity fluctuates inversely in relation to its cross-sectional area, which is necessary to keep the flow continuous.

  1. Bernoulli’s Equation: P + ½ρv2 + ρgh = constant

It is possible to calculate the value of gh by using Bernoulli’s Equation, which states: P + ½ρv2 + ρgh = constant.

In this equation, the velocity and pressure of a fluid may be determined by analyzing it as it travels through a tube. Fluid pressure is lower in fast-moving parts than in slow-moving sections of a varying-diameter horizontal tube. Bernoulli’s equation applies energy conservation concepts to a moving fluid. Hydrostatic pressure (P), (liquid density), v (velocity), g (gravitational acceleration, 9.8 m/s2), and h (liquid height) are all variables in this equation.

  1. Ideal Gas Law: PV = nRT

There are several different gas laws that are combined into the ideal gas law to explain how an ideal gas acts. There are four variables in this equation: P stands for pressure, V stands for volume, n stands for moles, R stands for the universal gravitational constant, and T is for temperature in Kelvin. The units you choose in the calculation will affect the value of R.

  1. Boyle’s Law: PV = constant, P1V1 = P2V2

Gasses have an inverse relationship between their volume (V) and their pressure (P) at a given temperature, according to this gas law. Using Boyle’s Law, you can predict how well the pressure of a given will vary as the pressure imposed on it varies.

  1. Charles’ Law: V/T = constant, V1/T1 = V2/T2

The volume (V) of a gas is proportional to temperature (T) according to this gas equation while the pressure remains constant. You can use Charles’ Law to predict how a gas’s volume will vary as its temperature varies, and the other way around.

  1. Avogadro’s Law: V/n = constant, V1/n1 = V2/n2

The volume of a gas is directly proportional to the number of moles present in the gas, according to this gas equation. As the number of moles in a gas increases, its volume decreases. Moles take up a bigger volume at the same temperature and pressure. Calculating the volume flow rate in relation to the number of moles is easy according to Avogadro’s Law.

  1. Avogadro’s Law: V/n = constant, V1/n1 = V2/n2

For a gas combination, Dalton’s Law states that the maximum pressure (PTotal) represents the total of the various pressures (P1, P2, etc.) produced according to each gas.

mcat physics equations

4C – Electrochemistry and the components of electrical circuits

Energy conversion into electromagnetic forms, which may then be employed to execute chemistry processes or activities, is a major focus of this section of the content catalog. Also included is how electrical currents travel via the neurological system across extended distances.

  1. Coulomb’s Law: F = k(q1q2/r2).

Force among 2 electromagnetic energy may be measured using this law. Repugnance or magnetism between two substances is proportional to the product of their charges (q) and inversely proportional to the resistance of their distance (r2). Coulomb’s constant, k, appears in this formula.

  1. Constant Current: I = ΔQ/Δt

It follows that I = Q/t for constant current.  Calculate the circuit’s electrical current (I) as an electric charge (Q) runs through it for a certain amount of time (t).

  1. Ohm’s Law: I = V/R

Voltage and resistance are the two variables that Ohm’s Law uses to calculate the amount of current (I) passing through some kind of circuit (R). When the voltage is multiplied by the impedance in ohms, the current is the result.

  1. Resistivity: ρ = R∙A/L

This impedance equation shows that a substance’s resistance (R) in ohms, divided by its cross-sectional area (A), and multiplied by its height (L) equals the substance’s impedance (L).

4D – Light, noise, and matter interaction in four dimensions

An organism may employ light and sound interactions with matter to perceive its surroundings, and these connections could also be utilized to component suppliers’ information or images, both of which fall within the purview of this content category.

  1. Photon Energy: E = hf

A photon’s energy (E) in electromagnetic radiation is inversely proportional to the wavelength of the wave (f). Planck’s constant, h, is used in this formula.

  1. Snell’s Law: n1sinθ1 = n2sinθ2

When a light beam goes from one medium including one refractive index (n1) to some other medium with a lower refractive index, it changes direction according to Snell’s Law (n2). Using a surface normal, the angle (sin1) of incidence and the angle (sin2) of refractive index are evaluated with respect to each other.

  1. Lens Equation: 1/f = 1/p + 1/q

The Lens Equation summarizes the curving of different wavelengths via a narrow lens. The field of view of both the lens, the object’s distance from the lens, and the image’s distance from the lens are all included in this equation. The focal length of a convex lens is always positive, but the focal length of a concave lens is always negative, therefore you’ll need to be familiar with the equation’s sign conventions.

4E – Atomic chemistry, nuclear decay, atomic electronic properties, and atom biochemical activity

Here, you’ll find information about crystalline nuclei and how they would be used to forecast physicochemical characteristics, as well as elementary particles, atomic nuclei, and nuclear radiation. When it comes to the MCAT’s Chemical and Physical Foundations of Biological Systems part, there are no specific physics equations that you’ll need to master.

Tips for MCAT Physics Equations

Always keep in mind that passing the MCAT does not automatically imply that you will become a world-class physicist

However, although there are several MCAT physics equations or MCAT physics formulas that you’ll need to memorize and correctly comprehend for the MCAT, they represent just a small portion of all possible physics equations that occur in the real world. Furthermore, they aren’t the most difficult physics equations to solve, and they’re often utilized to address concerns that may be resolved in a short period of time by following a simple procedure. The chemistry and physics parts of the MCAT will be primarily concerned with simple physics equations and basic concepts, respectively.

It is critical to understand when and how to use these equations in a confident and time-efficient manner. As soon as you’ve learned all of the physics equations you’ll need for the MCAT, start attempting to complete as many chemistry and physics mock exams as you can to improve your test-taking abilities. Assume you’ll need to know the fundamental equations of physics: if you’ve already spent a few minutes on calculations, you should rethink your approach to tackling the problem at hand.

Units should be avoided

If you’ve just spent 5 minutes completing hard arithmetic only to discover that your solution isn’t one of the alternatives, what do you do? We’ve all been in that situation. After wasting five minutes and still not knowing the answer, you start to stress and worry that you’ll never find out what you’re supposed to do. In many circumstances, a simple unit conversion will provide the correct answer, or you may have just entered the incorrect units into your computation.

If you want to be successful on the MCAT in chemistry and physics, you must be able to convert between various units of measurement quickly and accurately without the use of a calculator. Avoid making errors on exam day by being acquainted with the process of rearranging formulae in order to compute for a certain variable.

Make use of your knowledge of physics in this situation

The utilization of living systems will be used in the verification of theoretical physics concepts. To put it another way, you will not discover questions on the MCAT that are similar to those on your collegiate physics examinations. There will be no in-depth 30-minute physics calculations conducted this year. It is intended that fundamental physics concepts, such as fluid circulation via the aorta in the heart, would be adapted to the human body. In order to be ready for the MCAT, it is important to think about how physics subjects might be applied to the live creature. You should investigate this more if you are unfamiliar with the relationship between physics topics and biological systems.

FAQs About MCAT Physics Equations

mcat physics equations

How long is the MCAT’s chemistry and/or physics section?

One of the MCAT’s 4 components is the science component, which includes chemistry and physics. The time limit for this portion is 95 minutes, with 59 questions to accomplish. 44 of the 59 questions in this section are based on passages. 10 passages on chemistry and physics subjects will be given to you, and 4 to 7 passage-based questionnaires were distributed to you after each reading. In addition, there will be 15 separate questions sprinkled throughout the text. 

When preparing for the MCAT, how much time should I spend studying physics?

If you want to start preparing for the MCAT, you’ll need to know your starting point. A comprehensive MCAT assessment exam is required for this purpose. As you begin your MCAT preparations, it’s critical to have a clear picture of where you are. The AAMC website has a full-length test you may utilize for your diagnosis. Take your assessment test in a setting that is similar to the one you will face on the day of the test. Assess your strong and weak points as you go through the findings of your diagnosis.

What was your score on the physics questions? What physics equations or topics eluded you while you were studying for your exams? Are you able to apply what you learned in physics to concerns about biology and the human body?

On exam day, what are the best methods of remembering physics equations?

It is common to discover that standard techniques of learning mathematics, such as memory cards, do not work for you while you prepare for the MCAT. Why not give it another go? Here are some other MCAT preparation strategies to consider:

  • Once you have memorized the equation, practice saying it aloud until you can do so without looking at your notes or notes from other students.
  • Attempt to express the meaning of an equation in the form of a sentence by expanding it.
  • Complete a few practice problems with the equation.
  • To determine whether the equations you’re having trouble with are comparable to those you’ve previously mastered, try putting them together according to the subject.
  • Ask a buddy if they know of any good mnemonic methods for remembering the physics equations you’ll need for the MCAT exam.

Remember that the key to memorizing an equation is to comprehend it completely. Go into detail for each component of the equation and make an effort to understand how each portion works together. Consider going back over your notes and re-examining any equations relevant to earlier lessons on the foundations of calculus. You may not be capable of learning equations if you have gaps in your prior knowledge.

When solving physics formulas for MCAT, may I use a calculator?

Practicing for the MCAT without the assistance of a calculator is critical since you won’t be allowed to use one on any portions of the test. It is critical that you prepare for the MCAT in a way that mimics the circumstances of the actual exam. The months coming up to the MCAT are ideal for honing your arithmetic skills, both mentally and by hand.

Will the MCAT need me to be able to draw free-body diagrams?

Unlike the SAT, the MCAT does not include any free-response questions that measure your ability to draw diagrams. Don’t skip practice drawing free body diagrams for force calculations if you’re taking physics multiple-choice exams; this knowledge will come in useful.

Is Physics enough to ace the MCAT’s physics section?

How well you fared in your AP Physics course will have a role in this question’s response. AP Physics should provide you with the same foundation in fundamentals of physics as you would get in an introductory physics course at a university. The diagnostic test is a great opportunity to see how comfortable you are with the MCAT’s physics equations and ideas. If your MCAT chemistry and physics scores are strong, you may expand on your AP Physics knowledge by reviewing essential equations and ideas. This will help you ace the exam. For those who took the AP Physics course, you may still need to examine how basic physics principles apply to biological systems.

I’m confused as to why just these equations are deemed crucial. Isn’t there more I should know?

Naturally, you may need more details, but you will be able to infer or deduce them more rapidly if you start with these fundamentals. If you don’t understand the basics, you won’t be able to infer or deduce the remainder of the information.

How often should I take the MCAT, and when should I do so?

The only time you should take the exam is if you are entirely prepared. Having a score in the 90th percentile or above on your practice tests implies that you have consistently achieved high marks.

Is it possible for me to educate myself in physics for the MCAT?

Member in full. Yes, it is a possibility. Similar to other scientific disciplines, the degree of information required for the MCAT was less than the level that is appropriate for Physics I/II in college. It is recommended that you visit the website Hyperphysics. Animated films are also beneficial, and there are several available on YouTube.

Why are MCAT physics equations included on the MCAT? Physics is simply one of several basic components that you’ll need to understand about the physiological processes of the pulmonary, circulatory, and neurologic systems in both health and sickness as a health professional. As a result, the MCAT physics sections of the MCAT provide you with a chance to show your comprehension of how basic scientific principles will relate to your future medical profession. One of the most important components of your MCAT preparation will be to begin memorizing and genuinely comprehending every one of the physics equations presented in this blog post.

Don’t forget to take our free MCAT practice test at Medtutor to get familiarized with the format as well as the questions of the actual exam to strengthen your knowledge and skills, as a result, enhancing your chance to pass the MCAT exam with a high score on your first attempt. Good luck to you!

Can You Use Calculator On MCAT? (In-Depth Guide)

Students may worry, "can you use the calculator on MCAT" while they study for the high-stakes medical school entrance exam. Here is the answer you need!

June 16, 2022

If you want to go to medical school, you already know that you must take the MCAT in order to get admitted. The MCAT is one of the most difficult admission examinations available.

You’ve been studying nonstop, and your MCAT exam date is approaching quickly. You’re aware that you’ll be assessed on science, as well as verbal and writing thinking abilities.

You’ll very certainly need to tackle some fundamental math questions as well, such as geometry, algebra, and statistics. This brings the question, “Can you use a calculator on the MCAT?”.

We prepared this article after hours of research to provide you with some pointers on how to pass the MCAT math section without using a calculator.

can you use calculator on mcat

Can you use calculator on MCAT?

The MCAT is an interdisciplinary exam that assesses your knowledge of a variety of subjects. It’s one of the most difficult examinations you’ll ever take, designed to assess your critical thinking and reasoning abilities.

Some questions will include mathematics problems in addition to passage-based questions. So, So, do you get a calculator on the MCAT, or Are calculators allowed on the MCAT?

The AAMC does not allow students to use a calculator on test day, which is one of the factors that make the MCAT difficult. This is not, however, a reason for concern.

Candidates must answer mathematical questions based on their understanding of physics, chemistry, and statistical reasoning, among other disciplines, to pass the MCAT. With certain ingenuity and effort, the exam may be done without using a calculator.

Why are you not allowed to use a calculator on the MCAT?

The possibility of cheating is the most obvious. Undergraduate students commonly utilize graphing and scientific calculators throughout their studies, and they are amazingly complicated. They’re essentially self-contained computers.

The MCAT is more of a thinking examination than a maths exam. The exam’s goal is to determine if candidates have the potential to attend medical school as well as the aptitude and desire to study for it.

The purpose of the test is to see how effectively students can read the supplied material, grasp it, and then address the problem without succumbing to the stress of an exam.

It assesses their ability to approach seemingly difficult issues and passages, apply their knowledge and come up with a suitable answer for each question. The ability of students to enter numbers into a calculator has little bearing on their thinking or problem-solving abilities.

Because the MCAT does not involve challenging math problems, many people feel that calculators are not permitted. This is not totally accurate. Many questions need good mathematics abilities.

Students are sometimes asked to calculate the pH of a solution in acid-base problems. This might require them to square their answer or complete a computation that would be much easier with a calculator.

The MCAT, on the other hand, expects students to come up with a better, maybe even simpler answer to such issues. The important assessment is to remain calm when confronted with a huge amount of numerical data that may appear daunting.

Thus, even without a calculator, mastering certain important mathematical strategies and knowing when to utilize them makes the MCAT math section extremely manageable. Allowing calculators would also make it more difficult for test takers to measure their ability to tackle complex topics.

Without a calculator, How to face the MCAT

Math without a calculator may appear tough at first, but it is not difficult to learn. During the test, you can still utilize mental math or rough paper to solve questions. If you’re not sure about your mental maths skills, it’s time to start performing some practice questions. After all, we were taught some of these ideas in elementary school, and a lot has happened since then!

The key to doing well on the MCAT Math exam is to practice basic methods and ideas for manipulating difficult problems and making them easy. Because you are not permitted to use a calculator, you will not be required to conduct any long calculations to arrive at your final answer. The numbers may appear confusing and jumbled at first look, but they can always be simplified with a few easy strategies.

What math will be tested on the MCAT?

The MCAT is largely made up of ideas that demand students to solve physics, chemistry, and other scientific topics using critical reasoning. Before you get too worked up, remember that you don’t need a calculator to answer these problems. Students will be required to complete questions without the use of any help, like with many previous assessment techniques. [1]

The Chemical and Physical Foundations of Biological Systems segment of the MCAT will cover the majority of the math. Basic algebra, trigonometry, and arithmetic, which you should have mastered in school, will be required to complete problems.

The MCAT does not include any calculus questions. You will be expected to answer physics and chemical issues using arithmetic.

To ensure that you grasp the calculations necessary on the MCAT, we recommend brushing up on some specific math questions. These arithmetic subjects should be comparable to those in your freshman and sophomore math studies.

How to pass the MCAT without using a calculator: 4 Tips and Tricks

can you use calculator on mcat

It is not easy to give up your beloved calculator. But you do not have an option while taking the MCAT!

The good news is that there are several strategies to prepare for the next task. Here are some strategies for doing well on the MCAT without using your calculator.

#Tip 1: Practices questions on mental math

When was the last time you had to mentally do simple math? It has been a while if you’re like most people. Many individuals have forgotten how to conduct fundamental math because they rely so much on calculators.

Spend some time getting acquainted with what you overlooked. Don’t be embarrassed to review basic math problems! It’s better to suffer now rather than during the MCAT.

A sketchpad is full of arithmetic solutions, a notepad, and a pencil.

While this may be frightening keep in mind that the MCAT is not a math test. It mostly covers science subjects such as physics and chemistry.

To perform well on the scientific questions, students will need to apply some basic math, but they will not be asked to complete high-level math. Because you will not be able to use a calculator on the MCAT, we advocate never using one throughout your MCAT preparation.

Because calculators will not be available during the test, you should put yours away when studying for the MCAT math. This will assist you in breaking the habit and improving your ability to solve arithmetic problems rapidly.

Every issue should be practiced without the use of a calculator. You should be able to perform simple math calculations by hand or mentally. You should get in the habit of mentally solving arithmetic problems. You may practice this strategy by doing the math in your everyday life.

For example, while shopping at the supermarket, you can mentally add up the contents in your basket to verify whether your estimates are right. If you pay cash, you may immediately calculate the difference and see how close you are when you get your chance.

To prepare for the test, you should understand how to use numbers in your daily life. The knowledge you obtain will aid in MCAT preparation and review questions.

#Tip 2: Learn how to simplify and focus on accuracy

With complex arithmetic problems, simplification is key (particularly if you do not have access to a calculator). One of the most beneficial things you can do is practice making estimations while doing the math.

This can be accomplished in a variety of ways. If you are working with a long equation, divide it into smaller, more digestible chunks. Determine the smaller variables, follow the steps in the correct order, and simplify as you go.

You can use basic estimates to help you accomplish arithmetic faster in most cases. The exam is lengthy, and there is insufficient time to perform extensive computations. 

Consider converting difficult fractions to decimals for such queries. With your scratch paper, you can change an otherwise mind-numbing calculation into something a bit more approachable in seconds.

You may even round up or down the numbers. Instead of decimals, concentrate on whole-number equations. This allows you to use your hand or head to get the solution.

Even if the number isn’t exact, you may check through the options and pick the one that comes closest.

Always remember that the MCAT math problems will be basic, so you won’t have to spend much time on them. You can only solve them using a pen and paper. Do not be turned off by complicated or large figures. The solution will always be straightforward. To succeed on the MCAT math problems, you must simplify.

#Tip 3: Make estimations

If the problem has certain numbers that appear to be troublesome, you can immediately round them to make them easier to manage. The key to doing well in this part is rounding numbers to make computations easier. Before immediately rounding your figures, make sure to go through the solution options.

If you believe the solution options are extremely close in value, you should be extra cautious. Always keep track of whether you rounded your numbers up or down. The real answer will be lower than your computation if you rounded up, and vice versa.

#Tip 4: Control your stress and your overall pace

Last but not least, spend some time working at your pace.

Because the MCAT is such a long exam, it is easy to become exhausted. This is especially true when confronted with a seemingly difficult arithmetic problem.

While taking the MCAT exam, keep in mind to pace yourself. Students must perform well on the MCAT and answer questions in a short amount of time.

We recommend getting a timer and timing yourself on each portion of the MCAT to see how long it takes you to answer each question. This may assist you in determining where you need to ramp up the pace.

You should understand how to use numbers in your daily life. The knowledge you obtain will aid in MCAT preparation and review questions.

When completing math-based tasks, if you feel like you are writing exceedingly intricate calculations on rough paper, you are probably wasting your time on one question. You don’t need an exact response, and if you can not figure it out, you should probably go on to the next question.

You will only have roughly 1.4 minutes per question in the Physical and Chemical Foundations segment. This isn’t a lot of time, especially if you’re pressed for time.

Aside from these tips, you should practice math questions without using a calculator first. Although the computations will be little, answering practice questions might help make them simpler. 

Study some previous ideas and include some math reviews in your MCAT preparation. Remember that each question is worth the same amount of points, so don’t be scared by the exam’s few calculations-based problems.

Conclusion

So, can you use the calculator on MCAT? The answer is No. Even though the MCAT does not include a calculator, the arithmetic component of the exam should not be intimidating. You’ll be OK if you stick to the main ideas outlined above and devote adequate study time!

Don’t forget to take our free MCAT practice test at Medtutor to get familiarized with the format as well as the questions of the actual exam to strengthen your knowledge and skills, as a result, enhancing your chance to pass the MCAT exam with a high score on your first attempt. Good luck to you!

What Is Math On The MCAT Test?

Though MCAT is basically a scientific test, you'll still need a strong grasp of math basics to do well.  So, what math on the MCAT will you be tested for? 

June 15, 2022

The MCAT is a test that assesses your science knowledge as well as your ability to read critically. However, many of the scientific questions, particularly those involving physics and chemistry, may ask you to perform calculations that may require the use of a calculator.

Is it, however, permitted to use a calculator on exam day?  What math on the MCAT will you be tested for?

This complete guide will walk you through a series of arithmetic abilities, from understanding concepts to using methods to pass the exam without using a calculator.

math on the mcat

Does the MCAT have Math?

Is Math on the MCAT? Yes, absolutely.

The MCAT challenges you to complete math questions based on chemistry, physics, and statistical reasoning knowledge, among other areas. One of the MCAT’s problems is that you will not be permitted to use any type of calculator on Test Day. 

Although there are very few heavy calculations on the current MCAT, there are numerous questions that need you to demonstrate your ability to handle some math.

No calculators imply that all calculations, regardless of the MCAT part, must be done mentally. The MCAT will not assess you on tough math, and the most of answer selections will be placed far enough apart numerically that you may be able to skip complex calculations entirely if you have excellent estimate abilities.

Math is essential on the MCAT. Consider yourself in a circumstance where you are given a calculation question that you know how to solve but cannot do it perfectly in the available time. 

MCAT test students sometimes underestimate the mathematical skills necessary and end themselves in such situations. Math skills, like most other skills on this exam, may be developed with adequate familiarity and practice.

What math is on the MCAT?

As previously said, you are not allowed to use a calculator on the test day, there are questions on the test that will involve mathematical calculations, especially in the context of chemistry and physics. By strengthening your mathematics skills, you will greatly boost your ability to answer these exam problems.

While many of these math skills cover fundamental addition, subtraction, multiplication, and addition, this part gives a few extra topics to review for the MCAT, such as logarithm principles and fraction manipulation. We’ve included many practice problems at the conclusion of this article for you to try.

#1 Estimating and rounding numbers

Estimating and rounding numbers are important MCAT skills because they allow you to solve issues more effectively. This section offers crucial reminders to help you estimate and round.

Multiplication

Assume we’re attempting to multiply 3.64 x 7.35. How can we accurately approximate this result in a short period of time without a calculator?

When multiplying numbers with multiple nonzero digits, rounding might provide us with more acceptable results. We can substantially simplify our mathematical calculations by rounding these figures to one decimal place or a full integer.

It may be wise to look at the answer selections first to decide how much to round numbers. If the answer options are close together, we should round to one fewer digit to make our estimates more exact. We even can get away with rounding more if our answer options are more apart.

We can additionally correct for rounding for each digit to keep our results accurate. If we round a number up, we need to round the other number down to get closer to the exact value. For example, if we round 3.64 to 3.6, we should round 7.35 to 7.4 as well.

Assume we choose rounds 7.35 to 7.3 instead. How does this compare to the right answer and the answer given by 7.4?

3.64 x 7.35 = 26.754

3.6 x 7.4 = 26.64 => 26.6

3.6 x 7.3 = 26.28 => 26.3

When we apply 7.3, our calculation deviates quite much from the correct answer. So, we will come closer to the correct answer of 26.754 by accounting for rounding and applying the digit 7.4.

Division

Estimating and rounding division questions are comparable to estimating and rounding multiplication issues. As with multiplication, we initially examine the answer options to decide how much to round.

However, in the division, we apply other changes to accommodate for rounding. To maintain our numbers proportionate, we should move the dividend and divisor in opposite directions.

Let us suppose we wish to divide 20.97 by 2.78. If we choose to round 20.97 to 21, we should also round 2.78 to 3. This yields a result of 7, which is close to the true answer of 7.54.

Example problem

Let’s go over an example of a mathematics issue that may appear on the MCAT.

6.19 g of solid hydrochloric acid is added to 0.0500 L of water. What is the molarity of the end result?

Molarity is expressed as moles per liter. To determine the molarity of this solution; first, determine the number of moles of hydrochloric acid (HCl). First, we estimate HCl’s molar mass.

1.008g/mol+35.45g/mol=36.458g/mol

To calculate molarity, divide this number by the volume of the solution.

6.19g/mol(36.458g/mol HCl)

6g/mol(36g/mol HCl)=0.1667g/mol

Molarity is calculated by dividing this number by the volume of the solution.

0.1667g/mol HCl0.0500L=3.33M HCl

As a result, the estimated molarity of the solution is predicted to be 3.33M HCl.

#2 Logarithms

Logarithm rules

Another mathematical topic that is likely to occur on the MCAT is logarithms. Because these equations are the inverse of an exponential function, they follow the same rules. Here are some key principles and operations to grasp while working with logarithms:

  • The log of 1 is always 0: logx1 = 0
  • The base number’s log always equals 1: logxx = 1
  • The log of 2 variables equals the total of the logs of the individual factors as long as the base numbers are the same: logn(x y) = logn(x) + logn(y)
  • Similarly, the log of a fraction is the difference between the logs of the dividend and divisor: logn(x y) = logn(x) – logn(y)

Common logarithmic applications

One example of a common logarithm is with base “e.” These logarithms are referred to as natural logarithms and are represented by the symbol ln ().

Base 10 logarithms are also quite prevalent. You should be quite comfortable with and approximating logarithms in base 10.

It is vital to know that the prefix p stands for –log on the MCAT. pH, for example, equals -log[H+], while pOH equals -log[OH-].

Decibels are also a popular logarithmic use on the MCAT. Decibels (dB) are a unit of measurement for sound level. It can be determined using the following formula:

dB = 10log(II0)

where I = intensity of the sound, in Wm2

I0 = threshold of the lowest audible sound to a healthy human, equal to 10-2Wm2

The Henderson-Hasselbalch formula is a popular logarithmic application on the MCAT. This formula, which can be obtained from the equilibrium constant expression for the dissociation of a weak acid, enables us to do buffer calculations. Here is the Henderson-Hasselbalch equation:

pH = pKa+log(AHA)

What Is Math On The MCAT Test?

Example problem

Let’s look at an example of how logarithms may be used.

The pH of an HF solution (pKa = 3.2) is 4.8. What is the acid-to-conjugate-base ratio in the HF solution?

All of these values are related by the Henderson-Hasselbalch equation. We may use it to calculate the ratio.

pH = pKa+log(AHA)

To begin, we isolate our ratio on one side of the equation.

pH = pKa+log(AHA)

-1 (pH- pKa) =-1 log(AHA)

pKa-pH =log(HAA)

We may now enter our pKa and pH values.

3.2-4.8=log(HAA)

-1.6=log(HAA)

To calculate the ratio, we must use the exponential function, which is the inverse of the logarithm function. Because log() is the notation for base 10, we may add 10 to the numbers on both sides of the equation. Raise the number 10 to a logarithm with its own base, and the logarithm function on that side of the equation is essentially “canceled.”

10-1.6=HAA

In this solution, the ratio of HF to its conjugate base F is thus predicted to be 10-1.6. We may further estimate this value by identifying the range in which it should fall. While we don’t know the precise value of 10-1.6, we do know the precise values of 10-1 and 10-2:

10-2<10-1.6<10-1

1100<10-1.6<110

0.01<10-1.6<0.1

As a result, we’d seek for an answer choice that’s between 0.01 and 0.1.

#3 Methods for eliminating answer options

When dealing with calculation difficulties, it’s typically advisable to calculate an accurate solution first, then check to see if your result fits one of the answer choices. When you’re short on time, remember that you only need to choose one of four possible answers! Below are some pointers to assist you to increase your speed and accuracy while eliminating answer choices.

Scientific notation is a way of expressing numbers that include a significand and an exponent.

  • Any real number with an absolute value between 1 and 10, but not including 10, is significant.
  • Exponents are in base 10 and can be any whole number (i.e., negative, zero, or positive).

Significant figures

Using significant figure calculations, we can frequently remove answer options. When answer choices are presented in scientific notation, it is helpful to focus on the number of significant numbers in the significand.

Significant numbers indicate the accuracy of measurement depending on the measuring instrument. They must be taken into account in formulas. Significant numbers can be determined using the following rules:

  • All numbers are significant between the initial nonzero digit on the left and the final nonzero digit on the right.
  • When a number contains a decimal, the zeroes to the right of the final nonzero digit are important. When there is no decimal, the zeroes are meaningless. (For example, the number 4300.00 contains six significant numbers, yet the number 4300 has just two.)
  • Leading zeros, or zeros that come before the first nonzero digit, have no meaning. (For example, 0.010 has two significant numbers.)

Calculating with substantial figures necessitates the application of special principles.

  • Begin by noticing the place of the leftmost decimal point while doing addition and subtraction computations. After that, we proceed to solve the issue, keeping as many numbers as possible until the very conclusion of our calculation. Following this, we round the computed answer to the decimal point set in the first step.
  • To begin multiplication and division calculations, determine which factor, divisor, or dividend has the fewest significant digits. We then solve the issue, keeping as many digits as possible till the finish. Finally, we round the calculated answer to the number of significant digits of the first-step factor, divisor, or dividend.

Exponents

Exponents are also a way to eliminate answer options. Exponential functions follow the same laws as logarithmic functions since they are the inverse of logarithmic functions:

A0=1

AxAy=Ax+y

AxAy=Ax-y

(Ax)y=Axy

(AB)x=AxBx

A-x=1Ax

When answer options are stated in scientific notation, the exponent’s base number is always 10. To exclude answer choices for questions regarding extremely little or very big numbers, we can examine the exponent of this base number 10. 

For instance, if a question asks how many molecules are in a few moles of stuff, we should estimate a very big number. The answer will most likely contain an exponent raised to the 23rd power rather than the 5th power in this situation.

Example problem

Let’s put this information to use by solving a practice issue.

Calculate the molarity of 0.424 mol HI in 2.1 L of water.

First, determine which number contains the fewest significant digits. The amount of moles of HI has fewer significant numbers than the solution volume. Because the volume includes two significant figures, our final solution will have two as well.

We can now solve the issue without rounding up until the finish.

0424 mol Hl 2.1L=0.201M

This solution is then rewritten in scientific notation. We begin by adjusting the significand and multiplying by the appropriate base ten exponents. We multiply by 10-1 since we moved the decimal one point to the right.

0.2019M2.01910-1M

To get our final result, we round this estimated value into two significant figures.

0.2019M2.010-1M

We can be sure to exclude any response options with significant positive integers in the exponent when removing answer options.

math on the mcat

#4 Fractions

You may be asked to answer fractional equations on the MCAT. Fractions are frequently used in the thin lens equation and the solution of optical systems.

Subtraction and addition

We apply our operations to the numerators and maintain the denominator when adding and subtracting fractions. Before continuing with our calculations, we must remember to identify a common denominator. This is critical for maintaining the balance of a fraction.

We seek for the least common multiple of the denominators we’re dealing with to find a common denominator. The lowest number in which both denominators are factors is known as the least common multiple.

For example, suppose we want to combine the following fractions:

23+19

We must determine the lowest integer in which both 3 and 9 are factors. Because both 3 and 9 are factors of 9, the least common multiple is 9.

2/3 is now rewritten as a fraction with a denominator of 9. To keep the fraction proportionate, we must do the identical procedure on the top and bottom. The denominator must be multiplied by three to provide the desired result of nine, therefore we multiply the top by three to obtain six. We may begin adding after translating 2/3 to 6/9.

69+19=6+19=79

Division and multiplication

We multiply the numerators and denominators to get our result using multiplication. We don’t need to identify a common denominator before multiplying in this example. 

Nevertheless, before multiplying, we may sometimes reduce our calculations. We start by seeing if either element can be simplified on its own. Then we test if any fraction’s numerators can be simplified using denominators from other fractions, or vice versa. After that, we’ll start calculating.

If we’re multiplying the following fractions, for example:

271416

We may begin by reducing 14/16 to 7/8. The following is a rewrite of our multiplication problem:

2778

From this, we will simplify by dividing the denominator of one fraction by the numerator of another. You should note that the number 7 divides both the denominator and the numerator of the first and second fractions.

Furthermore, the number 2 divides both the numerator and denominator of the first and second fractions.

We now have the following multiplication issue to solve after simplifying these fractions:

1114

We combine all values on the top half of the fraction together and all values on the bottom half of the fraction together in fraction multiplication:

1114=1114=14

The correct answer is 1/4.

Multiplication and division are comparable operations. We multiply by the reciprocal of the divisor while dividing. For instance, consider the following fractions:

1347

Multiply the first fraction by the reciprocal of the second fraction to finish (74). Then, like with multiplication, we will proceed as follows:

1347=1374=1734=712

The correct answer is 7/12.

Thin lens equation application

On the MCAT, the thin lens equation is popular fraction math and physics application.

The thin lens equation connects three geometric optics lengths: focal length, object distance, and image distance.

  • The focal length (f) of a lens or mirror is the distance between the focal point and the center.
  • The object length (o) is the distance between the object and the lens or mirror’s center.
  • The image distance (i) refers to the distance between the picture and the lens or mirror’s center.

The following is the thin lens equation:

1f=1o+1i

where f = focal length

o=object distance

and i=image distance

Each variable’s sign includes information about its position.

  • Positive focal lengths are found in concave mirrors and converging lenses, whereas negative focal lengths are found in convex mirrors and diverging lenses.
  • When the object is in front of the mirror or lens, positive object distances occur; when the item is behind the mirror or lens, negative object distances occur. The object distance is positive in practically all MCAT-related applications.
  • The image is in front of the mirror or behind a lens if the image distance is positive. A real image is always inverted and is referred to as such.
  • If the image distance is negative, the picture is in front of a lens or behind a mirror. This type of picture is a virtual image that is always upright.

Remember to apply the same procedures to both sides of an algebraic equation, such as the thin lens equation. For example, if we remove 4 from one side of the equation, we must likewise subtract 4 from the other. This maintains the equation’s equilibrium. Failure to do so may result in an inaccurate answer!

Example problem

Let’s try out the thin lens equation in practice.

Assume a 4 cm focal length converging lens is placed 6 cm distant from an item. Determine if this lens produces a real or virtual image.

Begin by jotting down an equation you’re already familiar with: the thin lens equation.

1f=1o+1i

This problem requires us to calculate the image distance, or i. By removing 1/o from both sides of the equation, we may isolate that variable on one side of the equation.

1i=1f1o

We can now evaluate the formula using our previously calculated values for f=4 cm and o=6 cm. Then, we rearrange these fractions with a common denominator to remove these values. In this case, we use  4×6 = 24.

1i=14cm-116cm-1

1i=624cm-1424cm-1

Continue assessing the expression:

1i=6-424cm-1

1i=224cm-1

This gets us a little closer to figuring out i. To get an exact number for I we must simplify these formulas without using fractions. Fortunately, we can cross-multiply here: multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction and vice versa.

124=2i

24=2i

242=i

i=12 cm

We know the image is real since our image distance is positive i > 0.

#5 Questions and answers based on passages

Students were required to conduct a titration experiment using acetic acid as an analyte and sodium hydroxide as a titrant in a college laboratory. 

A burette was filled with 100 mL of 0.200M NaOH for the experiment. An Erlenmeyer flask containing 50 mL of unknown strength acetic acid was put beneath the burette. The concentration of the given acetic acid (pKa = 4.7) had to be determined by the students.

While doing the assigned experiment, one of the students develops the titration curve below.

math on the mcat

Question 1: At the equivalence point of the student’s titration, how many moles of NaOH were contained in the burette?

  1. A) 0.029 mol
  2. B) 0.03 mol
  3. C) 0.01 mol
  4. D) 0.014 mol

The correct answer is D.

The Erlenmeyer flask was filled with 28 mL NaOH at the equivalency point, keeping 72 mL in the burette 100mL – 28mL = 72 mL. The following equations are used to calculate the number of moles in 72 mL NaOH.

72 mL1 L1000 mL0.200 mol/L=0.0144 mol

We must round our answer to two significant figures because one of the original values (72 mL) contains two significant figures. 0.014 mol is the right answer.

Question 2: To make the titration solution, how many grams of NaOH were added to 100 mL of water?

  1. A) 0.5 g
  2. B) 0.8 g
  3. C) 1.2 g
  4. D) 0.3 g

The correct answer is B.

Our methods are identical to those used in the last problem. In this example, we must find out the number of grams in one mole of NaOH in addition to the total volume of NaOH in mL.

The atomic mass of Na is 22.99 grams per mol, which we should round up to 23 grams per mol. 

The atomic mass of O is 15.99 grams per mol, which we’ll adjust up to 16 grams per mol. 

The atomic mass of H is 1.01 grams per mol, which we should round to 1 gram per mol.

NaOH has a molar mass of 23 + 16 + 1 = 40 g/mol.

At this point, we can apply dimensional analysis and the solution’s known molarity to figure out how many grams of NaOH to add:

100 mL1 L1000 mL0.200 mol/L40g/mol=0.8 g

Question 3: At the titration’s equivalence point, what is the approximate ratio of [HA] to [A-]?

  1. A) 103
  2. B) 10-4.3
  3. C) 103
  4. D) 110-3.3

The correct answer is B.

To get the ratio, we will apply the Henderson-Hasselbalch equation. The pH is roughly 9 at the equivalency point. Acetic acid has a pKa value of 4.7. The ratio of [HA] to [A-], or [HA]/[A-], is required in this question.

pH = pKa+log(AHA)

pH-pKa=log(AHA)

-1 (pH- pKa) =-1 log(AHA)

pKa-pH =log(HAA)

4.7-9=log(HAA)

-4.3=log(HAA)

10-4.3=HAA

Question 4: Is the concentration of acetic acid after the student has added 14 mL NaOH larger than the concentration of acetic acid after the student has added 28 mL NaOH by how many orders of magnitude?

  1. A) 6
  2. B) 7
  3. C) 106
  4. D) 107

The correct answer is B.

Around 14 mL NaOH, the pH is 2, and around 28 mL NaOH, the pH is 9. The difference between these values is 7, which signifies the order of magnitude difference between the two concentrations (choice D is correct). Instead of the order of magnitude, Answer C reveals the actual ratio of these differences.

Question 5: Assume that instead of acetic acid, the same concentration of formic acid (pKa = 3.7) was used in this experiment. What effect would this have on the pH of the equivalency point?

  1. A) The equivalency point would move up
  2. B) The equivalence point would fall
  3. C) There is no change
  4. D) Either A or C

The correct answer is B.

To solve this question, keep in mind that pKa is equal to –log(Ka); so, the greater the Ka value, the lower the pKa value. 

Formic acid has a greater Ka value than acetic acid because its pKa is lower. Because formic acid is a stronger acid, its conjugate base will be weaker and will not react as easily with water to make formic acid and hydroxide. The pH of the solution will fall as a result of the decreased generation of hydroxide (B).

#6 Standalone questions and answers

Question 1: Assume that a solution in a beaker has the following elements:

[HA] = 0.001, [A-] = 0.1 and pKa = 3.2

What is the pH of this solution, approximately?

  1. A) 10-1.2
  2. B) 10-5.2
  3. C) 1.2
  4. D) 5.2

The correct answer is D. 

To find the pH, we can utilize the Henderson-Hasselbalch equation. Three of the Henderson-Hasselbalch equation’s values are explicitly provided in the question stem.

pH = pKa+log(AHA)

pH = 3.2+log(0.10.001)

pH = 3.2+log(100)

pH = 3.2+2=5.2

Question 2: How many significant figures are there in the year 2090.10?

  1. A) 3
  2. B) 4
  3. C) 5
  4. D) 6

The correct answer is D. 

Count all three numbers to the left of the decimal point as significant using the criteria for significant figures. Since they are between two nonzero integers, the two zeroes in the hundreds and ones locations are likewise important. The hundredths place zero is next to a nonzero number, making it significant. There are six significant figures in all.

Question 3: In scientific notation, what is the number 909.90?

  1. A) 9.099 x 104
  2. B) 9.0990 x 104
  3. C) 9.099 x 102
  4. D) 9.0990 x 102

The correct answer is D.

The significand’s absolute value in scientific notation is less than ten. As a result, we rewrite 909.90 by shifting the decimal point two positions to the left. We increase the significand by a factor of 100 to compensate for this modification. D is the only option that does this while keeping the number of significant figures from the original notation. 

Question 4: Sound A has a decibel level of 200 and Sound B has a decibel level of 40. How many orders of magnitude greater is Sound A than Sound B?

  1. A) 5
  2. B) 16
  3. C) 50
  4. D) 160

The correct answer is B.

We can solve this question by utilizing the decibels equation. We can determine the intensity of each sound and then the ratio of both intensities to compare two distinct sound levels.

The intensity of sound A will be denoted as IA, while the intensity of sound B will be denoted as IB.
dB = 10 log(II0)

200 = 10 log(IAI0)

20 = log(IAI0)

1020=IAI0

I01020=IA

Then, 40 =10 log(IBI0)

4 =log(IBI0)

104=IBI0

I0104=IB

Thus, I01020I0104= IAIB

1016=IAIB

Sound A is 16 orders of magnitude higher than Sound B, according to the IA/IB ratio of 1016.

Question 5: A student is requested to make a hypochlorous acid sample weighing 43.6 g. (HClO). How much HClO should the student prepare?

  1. A) 0.237 mol HOCl
  2. B) 0.672 mol HOCl
  3. C) 0.831 mol HOCl
  4. D) 1.20 mol HOCl

The correct answer is C.

We use the molar mass of HOCl to calculate the number of moles in this given mass. First, we determine HOCl’s molar mass.

  • H has a molar mass of 1.01 g/mol. This can be rounded to 1 g/mol.
  • O has a molar mass of 15.99 g/mol. This can be rounded to 16 g/mol.

As a result, the molar mass of HClO can be estimated as:

1 g/mol H+16 g/mol O+35.45g/mol Cl=52.45g/mol HOCl

To figure out how many moles are in a sample with a known mass, divide the mass by the molar mass.

43.6g HOCl(52.45g/mol HOCl)

We can now rule out option D since 43.6 is less than the number being divided by (52.47), implying that the answer to this division issue must be less than 1.

We can round down our numbers to the closest 10 because the response choices are so widely apart. This should result in a ratio that is easy to compute.

40g HOCl(50g/mol HOCl)=0.8 mol HOCl

Figure choice C gives 0.831 mol, which is quite close to this approximated answer.
