Is the MCAT hard? The short answer
Yes, the MCAT is hard. It’s a 7.5-hour, 230-question, passage-based exam covering biology, biochemistry, general and organic chemistry, physics, psychology, sociology, and critical reading, and most students need 300–400 hours of preparation. Scoring 511 or higher puts you in roughly the top 20% of test takers, near the average for medical school matriculants.
You’ve no doubt been asked by your premed advisor and friends, “Have you taken the MCAT yet?”
Their voices probably convey an optimism that you have already taken—and aced—the exam mixed with the fear that it still lies ahead of you. Meanwhile, you’ve also certainly heard horror stories about how hard the MCAT is.
Adding to the pressure, the MCAT plays a huge role in what medical schools look for in an applicant.
For the 2025–2026 academic year, the average MCAT score for medical school applicants was 506.3, whereas the average MCAT score for medical school matriculants was 512.1. The numbers show that being ahead of the pack greatly influences your odds of getting into medical school.
If you haven’t yet begun studying for the exam, the MCAT has a mysterious aura. It’s one of the last obstacles that you must face on your premed journey—and it’s notoriously difficult. We routinely get asked “Why is the MCAT so hard?” and even hear questions like “Is the MCAT too difficult?”
While the exam is very challenging, the MCAT isn’t too difficult. Each and every year, plenty of our students do well on the MCAT, making them even stronger candidates for medical school.
Nevertheless, it’s time we take a deeper dive and answer the following common question: Exactly how hard is the MCAT?
We wrote this guide to break down the reasons why students find the MCAT challenging. Plus, we’ve included study strategies you can use to solve those challenges and achieve your dream MCAT score.

What is the MCAT?
The Medical College Admission Test (MCAT) is a standardized, computer-based, multiple-choice exam that aspiring doctors take to apply to medical school in the U.S. and Canada. Administered by the Association of American Medical Colleges (AAMC), it tests your knowledge of the natural, behavioral, and social sciences, along with your critical reading and reasoning skills, across four sections scored from 472 to 528. Nearly all U.S. medical schools and most Canadian schools require MCAT scores, so learn more in our MCAT Ultimate Guide.
How hard is it to get a good MCAT score?
If a 511 is what most successful applicants get, how hard is it to get a 511 on the MCAT? A 511 on the MCAT currently corresponds to the 82nd percentile, meaning that roughly 1 in 5 test takers score 511 or higher. Clearly, scoring well on the MCAT is hard if you do not study properly.
If you master high-yield content, take lots of test-like practice problems in test-like conditions, and study exactly what you miss, it is more than possible for you to score very well on the MCAT and increase your chances of getting into your dream medical school.

Why is the MCAT so hard? 4 reasons
The MCAT is a hard test, but it’s manageable if you approach it diligently and efficiently. In other words, you’ll need to work hard and smart. Let’s look at what makes the exam more challenging than other tests you might have taken or heard of.
It’s 7.5 hours long (MCAT vs. SAT, ACT, LSAT, DAT, GRE, and GMAT)
The MCAT’s testing time is 6 hours and 15 minutes while the total seated time is just over 7.5 hours. This makes the exam much longer than its standardized testing counterparts.
For comparison, let’s look at the length of other popular standardized tests:
| Standardized Test | |
|---|---|
| MCAT | |
| SAT | |
| ACT | |
| LSAT | |
| DAT | |
| GRE | |
| GMAT |
As you can see, the MCAT is well over three times as long as the GRE and more than twice as long as the GMAT. Even when compared to the most similar test in this list, the dental admission test (DAT), the MCAT lasts almost 43% longer. Suffice to say, taking the MCAT is a marathon, not a sprint. The amount of information you’ll be tested on is clearly extensive.
It covers 7+ subjects across 4 sections
Here’s a breakdown of the four sections of the exam and the format of each:
| MCAT Section | |||
|---|---|---|---|
| Chem/Phys | |||
| CARS | |||
| Bio/Biochem | |||
| Psych/Soc |
If you’re wondering how many questions are on the MCAT, it contains 230 total questions that cover many different subjects, including:
From this list, you can see that some of the subjects are quite different. For example, the methods you use to study for sociology will have to change for organic chemistry. As a result, your MCAT study approach should be different from your approach to other exams. Specifically, you must master many varied subjects, not just one.
For the MCAT, however, mastery does not mean knowing every minor detail about every small fact in a biology textbook. Yes, you will need to know some important details, but more importantly, you will need to apply your knowledge about biology to information that the MCAT introduces in a passage. That brings us to the next reason why the MCAT is a harder-than-average exam.

Nearly every question is passage-based (and all multiple choice)
The MCAT’s mostly passage-based format means that almost all questions on the exam will be associated with a six- to seven-paragraph passage. This adds a layer of complexity to the exam—you won’t be able to simply recall facts that you have memorized in order to answer questions correctly.
Instead, you will need to synthesize information from the passage and interpret graphs in the context of your background knowledge. For example, the MCAT will require you to know not only a biological process such as glycolysis, but at the same time understand a passage and answer a question that draws on both outside knowledge and information from the passage.
It’s also worth keeping in mind that the MCAT is entirely multiple choice. Every one of its 230 questions has four answer options, and there’s no essay or writing section. That might sound like it makes the test easier, but the AAMC writes its wrong answers to be tempting: they’re often true statements that don’t answer the question, or they’re contradicted by a detail in the passage. Because you’re scored only on the number of questions you answer correctly, with no penalty for guessing, you should never leave a question blank. Earning a high score depends on learning to eliminate distractors quickly rather than simply recognizing a familiar fact.
The timing is tight
Because the MCAT asks a lot of questions in a relatively short period of time, students often struggle to finish some sections of the exam (e.g., Chem/Phys and CARS) in the allotted time, which leaves points that they could have earned on the table. As a result, reading comprehension and the ability to quickly analyze graphs will make a huge difference in your score, and this explains why even students with a 3.9 GPA are not guaranteed success on the MCAT.

Which MCAT section is the hardest?
For most students, the hardest MCAT section is either Critical Analysis and Reasoning Skills (CARS) or Chemical and Physical Foundations of Biological Systems (Chem/Phys). CARS is often the hardest to improve because there’s no content to memorize. Chem/Phys is often the most intimidating because it combines physics, general chemistry, and math under tight time pressure. Which section feels hardest for you depends mostly on your academic background. Each section is scored from 118 to 132, and the four scores are added together for your total of 472 to 528.
| Section | ||
|---|---|---|
| Chem/Phys | ||
| CARS | ||
| Bio/Biochem | ||
| Psych/Soc |
Why CARS feels hardest to many students. In the science sections, you can raise your score by learning more content. In CARS, every answer must be supported by the passage, so improvement comes only from practicing how you read, reason, and eliminate answer choices. That progress tends to be slower and less predictable, which is why we recommend practicing CARS consistently from the very start of your prep. Our MCAT CARS strategy guide explains how.
Why Chem/Phys feels hardest to others. Chem/Phys tests the subjects most premeds took earliest in college, such as physics and general chemistry. It also asks you to do math by hand, with no calculator. Reviewing core equations and practicing estimation can make this section feel much more manageable; see our MCAT physics and MCAT chemistry guides.
Don’t overlook Psych/Soc. Psych/Soc has a reputation as the “easiest” section, which is exactly why students lose points there. It rewards precise knowledge of terminology, and many answer choices describe closely related concepts. Studying it as seriously as the sciences is one of the simplest ways to raise your total score. Start with our MCAT psychology and sociology guide.
The best way to find your hardest section is to take a full-length diagnostic exam early in your prep and compare your four section scores. Then build your study schedule around your weakest area rather than the one you enjoy most.

Is the MCAT curved? How MCAT scoring works
The MCAT is not curved against the other people who take the exam on your test day. Instead, it uses a scaled scoring system. Your raw score is simply the number of questions you answer correctly, with no penalty for wrong answers. The AAMC then converts that raw score to a scaled score through a process called equating, which adjusts for small differences in difficulty between test forms. So if you get a slightly harder version of the exam, you may be able to miss a few more questions and still earn the same score as someone who got an easier version.
Your score report also shows a percentile rank for each section and for your total score. The percentile is the one part of your score that compares you to other test takers. It tells you what percentage of examinees scored at or below your score, and the AAMC updates percentile ranks every year using data from recent test takers. A total score of 500 is in the 48th percentile, while a 511 puts you in the 82nd percentile. To see how your target score compares to what medical schools expect, read our guide on what a good MCAT score is.
Is there a passing MCAT score? Can you fail?
No, there is no passing MCAT score, so you technically can’t fail the MCAT. Every test taker receives a scaled score between 472 and 528. However, a score well below a medical school’s typical range can effectively take you out of contention there. Each school sets its own expectations, and competitive applicants generally aim for at or above the average matriculant score of about 512.
If you’re not happy with your score, you can retake the exam. The AAMC allows up to three attempts in a single testing year, four across two consecutive years, and seven in your lifetime. Keep in mind that medical schools typically see all of your scores, not just your best one. If you feel test day went badly, you can choose to void your exam before leaving the testing center, which means it will never be scored or reported to schools. Before deciding to retest, read our guide to retaking the MCAT.

Is the MCAT getting harder?
The MCAT has changed substantially over the years since it was first used in 1928. While it has always been a difficult exam, the majority of the changes it has seen are updates meant to reflect the new developments in medicine and scientific knowledge that an aspiring doctor will need to know.
We’re unaware of any hard data suggesting that the MCAT is getting harder. However, during the latest round of changes that went into effect in 2015, questions in the behavioral and social sciences as well as more questions targeting reasoning skills were added along with questions in biochemistry.
This increased the length of the exam from a total of 200 minutes on the pre-2015 test to 375 minutes today. Your takeaway from this might be that it is indeed a more difficult test than before but the previous version was testing a different set of knowledge. Individual questions may have been harder but you weren’t tested as rigorously on your reasoning ability.
Ultimately, whether or not the MCAT is harder than before, your final score will attest to your ability relative to other test takers in your year. What really matters is how your score stacks up against other applicants for medical school. You might need more preparation time for today’s MCAT but it is covering the foundational knowledge you’ll need to succeed in modern med schools.

How hard will the MCAT be for you?
Each test-taker’s individual situation will be a factor in how difficult the MCAT is for a med school aspirant. This can both increase and decrease the difficulty depending on how you approach handling your preparation and manage your stress regarding the exam.
Your major, schedule, and prep method
There are other individual-specific factors that might make the MCAT easier or more difficult for any given person. Here are some of these factors (disclaimer: every single one of these factors can be overcome based on how you study for the exam, and there are counterexamples for each one we have listed!):
Undergraduate major: An English major may perform better on the CARS section while a Biochemistry major may perform better on the Bio/Biochem section
Other time commitments while studying: A student who is just studying for the MCAT will have more time to devote to the exam than a student who is in school, volunteering, and studying for the MCAT at the same time
Method of preparation: A student who prepares efficiently by prioritizing high-yield practice over rote memorization of small details will likely perform better on the exam
Preparation time: A student who prepares for the recommended 300-400 hours will likely perform better than a student who prepares for 75 hours
MCAT difficulty for non-traditional students
Like many aspects of the medical school admissions process as a non-traditional student, taking the MCAT poses some unique hurdles that can increase the difficulty of achieving a high score.
For one, non-traditional students have often been away from academic life for some time and may need more time to refresh gaps in their knowledge and test-taking skills. Spending time focusing on core MCAT subjects such as biology, chemistry, and physics may be necessary to a degree that it might not be for a traditional applicant who has just recently finished those courses.
Furthermore, non-traditional applicants tend to have more responsibilities to manage around their study time. Familial, financial, work, and extracurricular obligations can all eat into a non-traditional applicant’s MCAT preparation time.
While these issues make acing the MCAT harder, they’re not insurmountable obstacles. Following a proper study plan and ensuring you set aside time each day to hit the books will translate into success on test day.
The psychological difficulty of the MCAT
The sheer amount of information you’ll need to retain as well as the degree of persistent incremental progress involved in preparing for the exam adds to the psychological stress many students experience. These factors can increase the perceived difficulty of the MCAT.
While psychological factors are ultimately subjective, there are ways to manage the stress and anxiety that preparing for the MCAT can cause.
Intensive study over an extended period of time can cause a lot of mental strain. It’s important to follow a study plan that builds in downtime to give your brain a break so it can properly absorb the information. You may also want to study in short, targeted bursts to help you maintain concentration and achieve better results. For example, using the Pomodoro technique is a good way to organize your study time for maximum benefit.
Taking care of your physical health will also support your psychological health and help you better prepare for the MCAT. It’s important to remember to eat right and exercise as this is a well-documented reliever of stress. You may also want to incorporate mindfulness practices into your daily routine to help keep you grounded.
Furthermore, maintaining a positive mindset is key. Remind yourself that while the MCAT is important, it’s only one part of the medical school admissions process. Your score on this test alone will not be the sole determinant of your success in getting into medical school, so don’t let the stress overwhelm you!
Also, keep track of your progress. When you finish a deep dive into a difficult subject, mark it off your list with a smile. When you take practice tests, keep a record of the questions you missed and where your score improves. Being able to look back at how far you’ve come can help banish negative thoughts from your mind about the MCAT’s difficulty.
----
How long should you study for the MCAT?
Your goal in prepping for the MCAT should be to get somewhere between 300–400 hours of study time, depending on your academic foundation, skill with standardized tests, and other factors.
This will require you to plan ahead and consider how you will balance your responsibilities with your need to review material for the exam. Keep in mind that to hit 300 hours studying 3 hours per day will take a little over 3 months, so it is a considerable time commitment that requires a good amount of persistence.
We encourage you to review our guide on developing the ideal MCAT study schedule for a detailed breakdown.
Can you take the MCAT without studying?
It is not uncommon to hear about students who want to take the MCAT without studying because they have performed well in their science classes. These students say that if they do poorly, they will study and take it again, but in the backs of their minds, they believe that they are prepared to perform well on an exam that they have not yet studied for.
The problem with this approach is that knowing science is not enough to score well on the MCAT. Scoring well on the MCAT requires practice with the test’s format and an understanding of the way the AAMC likes to ask questions. Why risk sending a low score to medical schools for the sake of not studying?
Cost-wise, signing up for a full-price MCAT exam is actually more expensive than purchasing all of the online AAMC practice materials. So, it is in your best interest to buy the AAMC practice materials and take the exam only one time instead of 1) spending more money on two full-price MCAT exams and 2) sending medical schools a score below your target.

How to make the MCAT easier: strategies from 528 scorers
Take at least five full-length practice tests
The length of the MCAT makes it mentally and physically draining. During the course of your test preparation, you should take at least five full-length exams under test-like conditions. Start the exam right at 8 a.m., take each of your breaks as you would on the real test, and treat each question and passage as if you were taking your real MCAT.
Make sure you take this exercise seriously and mimic the conditions of test day as closely as possible. Set up your scratch paper and pencils, do everything you can to create a quiet environment and even think about how you’ll get to the testing center. If you know you’ll need to drive there, make the drive part of your practice test as well. You’ll have an opportunity to make the commute and pay attention to traffic and parking conditions so that you won’t have any surprises during the real thing.
Come test day, you will be more than ready and the test will fly by!
Study each subject the way it’s tested
Let’s look at an example: Jeremiah is struggling on two MCAT subjects: organic chemistry and CARS passages on humanities. Will Jeremiah be able to study CARS the same way he studies organic chemistry? Of course not!
For organic chemistry, Jeremiah would be wise to write down important functional groups, memorize their structures, and learn how those structures are important for the different chemical reactivities of the functional groups. For example, Jeremiah should write down what a carboxylic acid is, memorize the structure, and understand that the carbonyl carbon is electrophilic because the oxygen pulls away electron density. As a result, a nucleophile can attack the carbonyl carbon and cause the hydroxyl (-OH) group to leave.
Without “memorizing” a specific mechanism, Jeremiah just reasoned through nucleophilic acyl substitution. He should repeat this process for the other highly tested organic chemistry functional groups to improve his performance on the Chem/Phys section of the exam.
What’s the most effective study strategy for Jeremiah to improve his CARS score? He won’t be able to draw out reactions or memorize functional groups for CARS. Instead, Jeremiah should focus on finding and attempting as many CARS humanities passages as he can. After each passage, he should do an intense review of what he missed and why he missed it to identify patterns in his wrong answer choices.
As you can see, the most effective way to study for CARS is very different from studying for organic chemistry.
Know whether the answer comes from the passage or outside knowledge
Understand whether the test-writers at the Association of American Medical Colleges (AAMC) want you to find the answer in the passage, use outside knowledge to answer the question, or utilize a combination of the two approaches.
For the Chemistry/Physics, Biology/Biochemistry, and Psychology/Sociology sections of the exam, you will need to ask yourself where the AAMC wants you to find the answer. By taking practice problems and thoroughly reviewing them afterwards, you will begin to understand what the AAMC expects of you on any given question. As a general rule of thumb, if you can’t figure out the answer to a question, return to the passage to make sure you didn’t miss a key detail.
For the CARS section, you do not need to know outside information, meaning the answer choice must be somewhere in the passage. Use this to your advantage—in order to choose an answer choice in CARS, there must be a piece of text evidence that directly supports the question.
Gain instant access to 4,000+ representative MCAT questions across all four sections to identify your weaknesses, bolster your strengths, and maximize your score. Subscribe today to lock in the current investments, which will be increasing in the future for new subscribers.
Use a section-by-section timing strategy
Develop and rigorously practice a timing strategy.
For the Chemistry/Physics, Biology/Biochemistry, and Psychology/Sociology sections of the MCAT, you should aim to spend 8 minutes per passage on the 10 passages and 1 minute per standalone question on the 15 standalone questions.
For the CARS section, you should aim to spend 10 minutes per passage on the 9 passages.
We have broken this down for you here:
| MCAT Section | ||
|---|---|---|
| Chemistry/Physics | Passage-based |
8 minutes/passage |
| CARS | ||
| Biology/Biochemistry | Passage-based |
8 minutes/passage |
| Psychology/Sociology | Passage-based |
8 minutes/passage |
You should practice this timing strategy whenever you take a practice passage in order to become familiar with the time constraints you will see on the MCAT. By the time you are in your seat on test day, you will be an expert at quickly navigating passages and pacing yourself through the exam.
Common MCAT prep mistakes that make the test harder
Many students make the MCAT harder than it needs to be through avoidable prep mistakes. The most common is spending too much time reviewing content and too little time practicing with real MCAT-style questions. Here are the mistakes we see most often, and how to avoid them:
Passively rereading content. Highlighting textbooks and watching videos feels productive, but the MCAT tests whether you can apply what you know. Shift to practice questions as early as possible, and use them to show you which content to review.
Taking practice tests without reviewing them. A full-length exam is only as valuable as the review afterward. For every question you miss or guess on, identify why: a content gap, a misread passage, or a timing problem.
Saving full-length exams for the final weeks. Building stamina for a 7.5-hour test takes time. Space at least five full-length exams throughout your prep, and take them under realistic test-day conditions.
Neglecting CARS and Psych/Soc. These sections count just as much as the sciences. Practice CARS passages consistently from day one rather than cramming them at the end.
Practicing without a timer. Untimed practice hides pacing problems until test day. Once you’re comfortable with the content, follow a section-by-section timing strategy on every practice set.
Studying without a schedule. Without a plan, it’s easy to over-study favorite subjects and run out of time for weak ones. Build a realistic MCAT study schedule around your diagnostic score and your target test date.

Common myths about MCAT difficulty
Over the years, we’ve met with many students who have similar misconceptions about how hard the MCAT is. These misplaced ideas can lead to overconfidence before the exam or unnecessary stress while studying. Having a clear idea of how much difficulty you’re about to face can do wonders for your preparation and performance.
Myth: The MCAT is an intelligence test
You may be surprised to learn that many students see the MCAT as a test of innate intelligence, thinking they can “figure out” the answers to questions through their reasoning abilities alone. This might work somewhat for the CARS section, but this approach is fundamentally dangerous as the exam is structured to test knowledge and skills acquired through study and practice. Essentially, med schools want to see how much of the hard information you have really internalized.
Myth: The MCAT is pure memorization
On the other hand, the MCAT is not solely about regurgitating information you’ve committed to memory either. As mentioned earlier in the example about Jeremiah, a study strategy that focuses just on memorizing is a losing strategy. Spend your time memorizing key information and use that to deduce the answer to questions you might not have expected. And remember, there will be surprises!
Myth: The MCAT only tests science
Sure, there’s a healthy amount of science-centered material on the test and you would be wise to ensure you feel solid on the core STEM subjects, but you can lose a lot of points if you neglect CARS or Psych/Soc. We’ve seen a lot of students wonder why they didn’t get the score they wanted only to find out that they barely studied for the social sciences sections which worked to their detriment.

How many questions are on the MCAT?
The MCAT has 230 multiple-choice questions across four sections: 59 in Chem/Phys, 53 in CARS, 59 in Bio/Biochem, and 59 in Psych/Soc. Most questions are tied to reading passages, while the rest are standalone questions. For a full breakdown, see our guide to how long the MCAT is.
How long is the MCAT?
The MCAT has 6 hours and 15 minutes of testing time, and your total time at the testing center is about 7.5 hours, including breaks, check-in, and the optional tutorial. That makes it one of the longest standardized admissions tests. Learn how the time breaks down by section in our guide to how long the MCAT is.
Can anyone take the MCAT?
The MCAT is intended for people preparing to apply to medical school or another health professions program, such as osteopathic, podiatric, or veterinary school. If you want to take the exam for another reason, you must request special permission from the AAMC before registering. Learn more about the exam and registration in our MCAT Ultimate Guide.
Is a 510 a hard MCAT score to get?
Yes, a 510 is a challenging score that places you in roughly the top fifth of test takers. It’s competitive at many medical schools, although it falls slightly below the average score of about 512 for students who matriculate. See where a 510 stands in our guide to what a good MCAT score is.
How many times can you take the MCAT?
You can take the MCAT up to three times in a single testing year, four times across two consecutive years, and seven times in your lifetime. Voided exams and no-shows count toward these limits, and medical schools typically see all of your reported scores. Before you consider retesting, read our guide to retaking the MCAT.
Final thoughts
It shouldn’t be sugarcoated—the MCAT is a notoriously difficult exam. However, with the right kind of concerted effort and a well-thought-out plan, achieving your highest score is absolutely within reach!
