What Is on the MCAT? Sections, Topics, Timing, and Prep Tips

The MCAT is a computer-based, multiple-choice exam used by medical schools to assess your readiness for medical training. This quick guide breaks down every section, the topics tested, timing, and smart ways to study.

MCAT at a glance

Total questions: 230
Sections: 4
Section timing: 95 min, 95 min, 95 min, 90 min
Testing time: 375 minutes
Seated time with breaks: about 7.5 hours

What the MCAT tests

You will be assessed on foundational concepts from biology, biochemistry, chemistry, physics, psychology, and sociology, plus your ability to analyze passages and reason from data. Most questions are passage based, with a smaller set of stand-alone “discrete” items.

What to study and how

Cover the blueprint, not just facts. Learn concepts to application level and practice interpreting figures, graphs, and experimental setups.
Use passage-based practice early. Train the skill the test requires.
Target discrete items for quick points. If helpful, answer them first within each science section.
Build an error log. Track patterns in misses and write the rule that would have prevented each error.
Rehearse test-day stamina. Simulate full-length timing, breaks, and nutrition.

FAQs

#1. Is the MCAT multiple choice?

Yes. All four sections are multiple choice with most items tied to passages.

#2. How many questions are on the MCAT?

There are 230 questions total. Three sections have 59 questions each, and CARS has 53.

#3. Do I need specific college courses before testing?

Not required, but introductory courses in biology, chemistry, physics, psychology, and sociology make preparation far more efficient.

#4. Is there math on the MCAT?

Yes. You will use algebra, proportions, logs, and basic statistics. Calculators are not allowed.

#5. Which topics feel hardest?

It varies by student. Many find CARS challenging since it tests reasoning without prior content, and Chem/Phys for its equation fluency under time.

#6. How is the MCAT scored?

Each section is scaled 118 to 132 based on exam difficulty, then summed for a total score of 472 to 528.
