The MCAT Explained: A Practical Guide for 2027 Applicants

The Medical College Admission Test, or MCAT, is one of the most important components of the U.S. medical school admissions process.

Administered by the Association of American Medical Colleges (AAMC), the MCAT evaluates scientific knowledge, critical reasoning and your ability to apply concepts to unfamiliar problems.

Most U.S. MD and DO programs require the exam, although some early assurance and combined-degree pathways offer exceptions.

What Does the MCAT Test?

The MCAT has four sections:

1. Chemical and Physical Foundations of Biological Systems

Tests concepts from general chemistry, organic chemistry, physics, biology and biochemistry.

2. Critical Analysis and Reasoning Skills (CARS)

Tests reading comprehension, analysis and reasoning through passages drawn largely from humanities and social sciences.

3. Biological and Biochemical Foundations of Living Systems

Focuses mainly on biology and biochemistry, alongside related chemistry concepts.

4. Psychological, Social and Biological Foundations of Behavior

Covers psychology, sociology and biological influences on behaviour.

The current exam remains a computer-based, multiple-choice assessment. (students-residents.aamc.org)

How Is the MCAT Scored?

Each section receives a score between 118 and 132. The four section scores are combined for a total score ranging from:472 to 528 The midpoint of the total scale is 500. There is no penalty for guessing, so you should answer every question.

The MCAT is also equated, meaning small differences in difficulty between different exam forms are taken into account when raw scores are converted to scaled scores. 

What Is a Good MCAT Score?

There is no single score that is considered good for every applicant.

A better approach is to compare your result with:

• The median MCAT scores of your target schools
• Your GPA
• Your science GPA
• Your academic trend
• The strength of the rest of your application

For context, recent U.S. MD matriculants have averaged around 512, while osteopathic medical school matriculants have averaged closer to 503.

A score that is competitive at one school may be well below the typical range at another.

Your target should therefore come from your school list rather than an arbitrary national cutoff.

When Should You Take the MCAT?

Take the MCAT when you are academically prepared and when the score-release date works with your application timeline.

For students applying directly from college, testing between January and May of junior year is common. However, students taking a gap year may choose a later date.

The most important readiness indicator is your performance on high-quality full-length practice exams. If your scores are consistently close to your target range, you are much more likely to be ready.

Scores are usually released 30–35 days after the exam. 

What Courses Should You Take Before the MCAT?

The MCAT draws from subjects commonly covered in:

• General biology
• General chemistry
• Organic chemistry
• Physics
• Biochemistry
• Psychology
• Sociology

You do not necessarily need to complete every possible prerequisite before beginning MCAT preparation, but you should have a strong understanding of the topics tested.

If you have not taken a relevant course, your study plan will need to include more time for learning the material rather than simply reviewing it.

How Long Should You Study for the MCAT?

There is no universal number of study hours required. Some applicants prepare over several months while taking classes or working. Others study more intensively over a shorter period.

A typical study plan may span three to six months, but what matters more is your progress.

A strong plan should include:

• Initial diagnostic testing
• Content review
• Passage-based questions
• Section practice
• Full-length exams
• Detailed review of mistakes

Do not judge readiness only by how many hours you have studied. Practice performance is a much better indicator.

Use Official AAMC Materials Strategically

Official AAMC practice materials are particularly valuable because they come from the organisation that creates the MCAT.

They include:

• Full-length practice exams
• Question packs
• Section banks
• Practice questions
• Official content outlines

Third-party materials can still be useful, especially earlier in your preparation, but official AAMC exams are usually the strongest resource for estimating how prepared you are for the real test.

The AAMC also provides official preparation resources through its MCAT Prep Hub. 

Focus on Application, Not Just Memorisation

The MCAT does not primarily reward memorising large quantities of information. Most questions require you to interpret passages, analyse experiments, combine information and apply scientific principles.

Effective preparation therefore involves both:

• Content knowledge: Understanding the underlying science.
• Reasoning practice: Learning how to apply that knowledge to unfamiliar scenarios.

Students who spend months reading textbooks without practising MCAT-style questions may know the material but still struggle with the exam itself.

Take Full-Length Practice Exams

Full-length exams help you evaluate more than content knowledge.

They test:

• Timing
• Concentration
• Stamina
• Section pacing
• Break strategy
• Performance under realistic conditions

The MCAT is a long examination, so endurance matters.

As test day approaches, complete full-length practice tests under conditions that resemble the actual exam as closely as possible.

After each test, spend time reviewing why you missed questions.

Ask whether the problem came from:

• Missing content
• Misreading the passage
• Incorrect reasoning
• Poor timing
• Changing a correct answer
• Failing to identify what the question was asking

This analysis helps turn practice into improvement.

What Happens on MCAT Test Day?

The MCAT testing experience lasts several hours and includes four sections with scheduled breaks.

Expect strict security procedures at the testing centre.

You should:

• Arrive on time
• Bring acceptable identification
• Follow testing-centre instructions
• Store prohibited belongings as directed
• Use only materials provided for note-taking

Calculators are not permitted.

At the end of the examination, you will also choose whether to have your exam scored or voided.

Review the current MCAT Essentials before your test because policies can change between testing years. 

How Much Does the MCAT Cost in 2026?

For 2026 testing dates, the standard MCAT registration fee is $355. Applicants approved through the AAMC Fee Assistance Program pay $145.

Testing outside the United States, Canada or U.S. territories adds a $130 international fee. 

Rescheduling fees depend on how close you are to your exam:

Changes cannot be made less than 10 days before the exam.

AAMC Fee Assistance

The AAMC Fee Assistance Program is designed for applicants who would otherwise have significant difficulty paying the costs associated with the MCAT and medical school applications.

Benefits can include:

• Reduced MCAT registration fees
• Free official MCAT preparation products
• Complimentary access to MSAR
• Additional AMCAS-related benefits

Approval must generally be received before purchasing services for the reduced fees to apply. 

How Many Times Can You Take the MCAT?

The AAMC limits attempts to:

• 3 times in one testing year
• 4 times during two consecutive testing years
• 7 times in a lifetime

Voided exams and no-shows can count toward testing limits. That is another reason not to take the MCAT simply to “see how you do.”

Prepare with practice exams first and sit for the actual examination when you have good reason to believe you are ready.

Do Medical Schools See Every MCAT Score?

Medical schools receiving your official MCAT history can generally see your scored attempts.

Individual schools may treat multiple scores differently. Some emphasise the most recent result, some consider the highest, and others review the complete testing history.

Because policies vary, check the admissions guidance of schools on your list before deciding whether to retake.

Do All Medical Schools Require the MCAT?

No, but most traditional U.S. medical school applicants will need it.

Exceptions can include:

• Certain BS/MD programs
• Early assurance programs
• Special institutional pathways

For example, accepted students in Mount Sinai's FlexMed Early Assurance Program do not take the MCAT.

These exceptions are relatively limited, so most students pursuing traditional MD or DO admissions should expect to take the exam.

How Does MCAT Preparation Fit With Pre-Med Experience?

MCAT preparation should not completely replace the other experiences that help you understand medicine. Medical schools also consider clinical exposure, service, research, leadership and other aspects of your background.

Experiences such as pre-health and pre-med clinical internships can help students develop a clearer understanding of patient care and healthcare systems alongside their academic preparation.

Plan your MCAT study schedule so that you can prepare seriously without abandoning meaningful long-term experiences merely to maximise study hours.
