2024 MCAT Study Guide — Everything You Need to Prepare


The MCAT is a critical piece of your medical school application that can make or break your chances of acceptance. It’s a grueling 7.5-hour test that requires significant hours of planning, studying, practicing, and preparing. Use our MCAT Study Guide to familiarize yourself with how the MCAT is scored and learn critical study strategies that will lead to test day success.

Below, we’ll cover MCAT basics, how the MCAT is scored, 7 MCAT study strategies, MCAT resources, and FAQs.


An Introduction to the MCAT Sections

The Medical College Admission Test, better known as the MCAT, is a 7.5-hour standardized exam for premeds designed to assess foundational science knowledge and critical thinking skills. The test is split up into 4 sections, each worth 132 for a total perfect MCAT score of 528.

Sections 1, 3, and 4 of the test require a deep knowledge of scientific facts and concepts, as well as an ability to combine knowledge from multiple disciplines with inquiry and reasoning skills.

On the exam, you will be asked to demonstrate the following skills:

  • Knowledge of scientific concepts and principles
  • Scientific reasoning and problem-solving
  • Reasoning about the design and execution of research
  • Data-based and statistical reasoning

Section 2 of the MCAT, CARS, is a little different. It doesn’t require any memorization; instead, it tests your critical analysis and reasoning skills. In this section, you are asked to read passages and then answer questions about those passages. To do well on the CARS section, you must be able to quickly understand, analyze, and evaluate what you read.

Chemical and Physical Foundations of Biological Systems (Chem/Phys)

The first section on the MCAT is worth 132 points with 59 total questions (44 passage-related,15 standalone.) It tests your knowledge of biology, biochemistry, general chemistry, organic chemistry, and physics in combination with your scientific inquiry and reasoning skills.

This section is broken down into the following testing categories:

  • First semester biochemistry: 25%
  • Introductory biology: 5%
  • General chemistry: 30%
  • Organic chemistry: 15%
  • Introductory physics: 25%

Chemical and Physical Foundations of Biological Systems

Critical Analysis and Reasoning Skills (CARS)

MCAT CARS student reading

The CARS section was developed to measure your analytical and reasoning skills. Unlike the other three sections, it’s not a section you can study for directly. It requires continual practice to hone your reading comprehension, analysis, critical thinking, and reasoning skills.

The section includes 9 passages, each between 500 and 600 words. For each passage, you will need to answer 5-7 questions for a total of 53 questions.

How Is the MCAT Scored?

The MCAT is broken down into 4 sections, each worth a total perfect score of 132 points. A perfect MCAT score combining all 4 sections is 528.

Each of the 3 science-related sections has 59 total questions (44 passage-related, and 15 standalone.) The CARS section is scored a little differently, but it is still worth the same amount of your total score—132 points. The CARS section has 9 passages, which each have 5-7 questions for a total of 53 questions.

MCAT Sections Breakdown


What’s a Good MCAT Score?

A perfect MCAT score is 528, which requires scoring 132 in each of the 4 sections. Of course, a perfect score is not required to get into your top-choice medical schools.

A good MCAT score is different for everyone and largely depends on the schools you hope to gain acceptance to. Average statistics for recently matriculated medical students will give you an idea of what’s expected, but you should always research exactly what is expected for each school you are applying to.

The average MCAT score for recent matriculants applying through AMCAS is 511.90

The average MCAT score for recent matriculants applying through AACOMAS is 504.31

The average MCAT score for recent matriculants applying through TMDSAS is 503.80

Remember that these are only averages. The actual score you need will vary by school, and to be competitive, you should aim for much higher than average for the best chance of acceptance at your top school.

MCAT Study Guide: Tips and Strategies

1 | Study Smarter, Not Harder With Active Studying

“Smarter, not harder” is a good rule for most things in life. Why put in more energy than you need to in order to succeed? It’s not about the sheer amount of time you spend studying. Carefully build a study plan that focuses on efficiency, effectiveness, and results.

More hours spent studying and simply “keeping busy” isn’t better and will likely end in worse results due to stress and burnout. You need to focus on what will yield the best results based on your own unique strengths and weaknesses, study preferences, schedule, and personal wellness.

Practice active versus passive study techniques. Although repetition is important, it takes much longer to consolidate key facts to memory than if you were to spend that same time practicing active learning, such as with practice questions and flashcards.

Make smart, tactical decisions about how, when, and what you study, and prioritize active study techniques in order to optimize any time spent studying.

2 | Establish a Study Routine

Routines are a critical aspect of an effective study strategy. Take time to establish a routine that works best for you. This should include routines around the time you spend studying and night and morning routines.

An effective routine will help you establish a study groove, improve your overall wellness, and enhance the quality of your studying. All-nighters, sugar rushes, and stressful study habits are not your friends. Start building healthy habits early as a premed to prepare for the MCAT as well as your time as a medical student.

3 | Focus on High-Yield Content

Studying more or for longer hours isn’t necessarily the best strategy. There’s a limit on how much can be memorized in a given period of time. To maximize effectiveness, focus on memorizing high-yield concepts—concepts that are most likely to have an impact on your MCAT score.

There are only so many productive hours of studying during a day, and the reason for putting less focus on low-yield concepts is the forgetting curve.

the forgetting curve

The forgetting curve reveals the reality of memory decay. No matter how hard you work to memorize MCAT facts, you will forget them over time. The forgetting curve is why students who spend over two months studying for the MCAT see diminishing returns and plateau with their score. After a certain point, you will learn at a rate almost equal to the rate at which you forget information.

Studying high-yield information is the best solution. Of course, how do you know what content is low-yield vs. high-yield? Speak to trusted mentors or peers who have been through the process before, and consider working with an MCAT tutor.

4 | Assess Your Strengths and Weaknesses

You don’t need to spend the same amount of time studying each section. Assess yourself to understand what you’re best at and where you need the most improvement. If you know you’re an ace at physics but struggle with chemistry, spend more time studying chemistry. If you feel very confident with all of your science knowledge but haven’t picked up a book for pleasure in years, focus on building your reading comprehension to prepare for the CARS section of the MCAT.

It’s not only about what you’re studying—it’s also about how you’re studying. Are your study habits working for you? Are you confident they’ll serve you well as you prepare for this monumental test?

It’s difficult to be completely confident in your study habits since you’ve never taken the MCAT before. But your mentors and MCAT tutors have. They can objectively assess your current strengths and weaknesses to help you create a customized study approach that’s tailored to what you need to improve most.

5 | Prioritize Comprehension

Yes, memorization is a key factor when preparing for the MCAT, and you will need to memorize a great deal of science content to be successful, but memorizing what you don’t understand won’t get you anywhere. It’s far less effective to memorize facts in isolation without first building a solid foundation of comprehension.

Performing well on the MCAT comes down to three important factors: understanding, memorizing, and applying. Once you understand a concept, you must commit it to memory. Then, you must apply your understanding and memorization in a standardized format.

If you memorize something without understanding it, you cannot effectively apply that knowledge. For example, it’s not enough to memorize the periodic table. You must also know how each element relates to each other, what factors influence them, and their specific significance. 

6 | Utilize Quality Tools and Resources

Utilize the many quality tools and resources that are available to you. You don’t need to start from scratch since so many people have taken the MCAT and mastered studying before you. There are plenty of quality tools and resources out there, such as AAMC, Memm, Med School Insiders, and the Khan Academy.

Read reviews of any resource you’re considering, talk to medical students, and ask your mentors for recommendations. Everyone has different strengths and weaknesses when it comes to studying. Capitalize on your differences by choosing tools that align with your needs. What’s important is finding quality tools and resources that work for you and sticking to those rather than trying to use all of them at once.

7 | Intentionally Limit Distractions

Thanks to our smartphones, computers, tablets, smartwatches, and what have you, distractions and interruptions are everywhere. Unfortunately, you may rely on this technology to help you study. In order to master your MCAT studying, you also need to master your distractions. This includes your email, phone notifications, messages, and the people in your life.

Interruptions are costly to your focus. It can take an average of 23 minutes and 15 seconds to get back to the task after an interruption. As any premed will attest, time is not something you have in abundance. It’s critical that you intentionally limit your distractions in order to gain deep chunks of focus.

You can adjust the notification settings on your phone, and most phones also have settings that help you limit the amount of time you spend on certain apps. Set limits for your own personal common offenders, which may be TikTok, Instagram, gaming, news aggregates, or other distracting apps.

If you need the extra push, set up a distraction blocker on your phone and computer to ensure you can’t access any distracting websites or apps during your study time. When it is time for a break, avoid the urge to turn to your phone and instead take the time for a stretch, walk, or healthy snack.

Where to Find MCAT Resources

When it comes to MCAT resources, AAMC is the best place to start.

MCAT Flashcards

MCAT flashcards accelerate your learning by providing clear blocks of information that are easy to retain and recall. Flashcards will help you master the knowledge and skills needed to succeed on the MCAT. We recommend using Memm to effortlessly organize information and accelerate your MCAT learning.

MCAT Practice Questions

Practice passages help you review and practice your knowledge and skills on a routine, regular basis. There are a number of resources to help you practice both CARS and the science-based sections of the MCAT.

MCAT Practice Tests

Practice tests aren’t all that helpful in the beginning, but they do play a critical role in helping you decide when you are ready to take the MCAT.


How to Perform Well on Test Day

It’s essential that you adequately prepare so that you are ready on test day and can go into the exam relaxed and at ease. All-nighters and rushing to study leading up to the moment of your test will not serve you. Here are some of our top tips for succeeding on test day.

  • Don’t change it up—stick to the routine and habits you have developed leading up to the test.
  • Ensure you get lots of sleep and maintain your regular sleep routine.
  • Eat brain-healthy foods and avoid sweets, sugary drinks, and fast food. (Note: It’s more important to stick to what you know. If you haven’t developed these healthy habits yet, don’t completely switch things up on the day of your test. It’s better to stick with what you know.)
  • Get someone to check on you when you need to be up just in case something goes wrong, such as a missed alarm.
  • Pack everything you need the day before your test, such as valid forms of identification, required medication, wallet, keys, snacks, etc.
  • Before test day, go to the testing location as a practice run. This will get you familiar with how to get there, parking, entrances, etc., so you’re not surprised by anything on the day of your test.
  • A week before test day, switch to reviewing the most important material. At this point, your focus shouldn’t be on learning new material.
