Do MCAT questions repeat? If you’re wondering whether a question from a practice test, a friend’s exam or your first attempt could show up on your test day, you’re in good company. Most of us on our team wondered the same thing!
The AAMC writes the MCAT, so we’ve kept every answer here to what the AAMC says in its own guides.
Below, we cover how MCAT test forms differ, where the AAMC reuses questions, and how to get ready for questions you haven’t seen yet 🙂
Do MCAT Questions Repeat?
The AAMC hasn’t said whether a scored MCAT question can appear again on a later test date. Its guides do describe three things that bear on repeats.
- Test forms differ. Each form uses different specific questions (AAMC scoring guide).
- Some questions are tryouts. Every section has unscored field-test questions.
- Past questions become practice. AAMC Practice Exams 1 to 6 use previously administered questions.
So you’ll meet previously used AAMC questions when you practice. On test day, the safest plan is to expect questions you haven’t seen before, and we’ll help you get ready for them!
Is Every MCAT Test Different?
The AAMC gives the MCAT on more than one test form. Every form measures the same basic concepts and skills, and each one uses different specific questions.
The AAMC works to keep the forms equal in difficulty. It also says one form may run slightly harder or easier than another.
Does Everyone Get the Same MCAT Exam?
Everyone gets the same four sections, the same timing and the same score scale. The questions can differ from form to form, and the AAMC doesn’t publish how it assigns forms to test takers.
That’s where equating comes in. The AAMC converts your raw score to a scaled score through equating, which evens out small differences in difficulty between forms. That’s good news for you!
Does the AAMC Reuse MCAT Questions in Practice Exams?
Yes. On its Official Prep page, the AAMC says free Practice Exam 1 and Practice Exams 2 to 6 each use questions from previously administered MCAT exams. It also says its Official Prep products are written by the test developers.
Its CARS Question Bank mixes 166 new questions with 409 from older CARS products. Our guide to the AAMC CARS Question Bank shows where every passage from the old packs went.
Because they come from past exams, the AAMC’s practice exams show you how actual MCAT questions read. Take them timed, in one sitting, and our MCAT practice test guide shows how to space them through your prep.
The free Unscored Sample Test gives you raw scores only, so convert yours with our MCAT score calculator!
The AAMC’s free Practice Exam Features tool walks you through the exam’s features, including optional keyboard shortcuts, with 12 example questions. Give it a go before test day!
What Field-Test Questions Mean for You
Every MCAT section includes some field-test questions, according to the MCAT Essentials. They don’t count toward your score, and the AAMC is considering them for future use.
The AAMC doesn’t list which questions are field tests. Its guidelines for discussing the exam also ask test takers not to speculate about which passages were field-test items.
So give every question your full effort, including the ones that feel strange or unusually hard!
Stuck on a passage that throws you? Make your best pick and go on to the next one. It may even be a field-test passage, and you’ve got points waiting further along 🙂
How Many Questions Are on the MCAT?
The MCAT has 230 questions across four sections, and every section is multiple choice. This is how the AAMC lays them out, in test-day order.
Each science section has 10 passage sets of 4 to 6 questions, plus 15 independent questions. CARS has 9 passage sets of 5 to 7 questions.
In full, the sections are Chemical and Physical Foundations of Biological Systems, Critical Analysis and Reasoning Skills, Biological and Biochemical Foundations of Living Systems, and Psychological, Social, and Biological Foundations of Behavior.
The three science sections mix passages with stand-alone questions, and every CARS question goes with a passage. Content time adds up to 6 hours 15 minutes, and the whole MCAT day runs about 7 hours 30 minutes with breaks (AAMC).
Our MCAT exam format guide covers each section in more detail!
How the MCAT Differs From the SAT and ACT
The SAT and ACT test the reading, writing and math you need for college. On the MCAT, medical school faculty, residents and students rated each concept as important to success in medical school, according to the AAMC.
It’s a content exam too. You’ll need introductory biology, general and organic chemistry, physics, biochemistry, psychology and sociology, plus the reading skills CARS tests.
Question length can fool you on the MCAT. A short question might take three or four steps, and a long one might have a quick answer!

How to Prepare for MCAT Questions You Haven’t Seen
Since you can’t count on seeing a question twice, build the skills that carry over to any question.
- Learn the high-yield content with our high-yield MCAT topics checklist.
- Work through content review on our MCAT content review dashboard.
- Practice with AAMC Practice Exams 1 to 6, built from previous MCAT questions.
- Review every miss with our guide to reviewing MCAT mistakes.
If you’d like a 515+ scorer to spot the patterns in your misses, 1:1 MCAT tutoring pairs you with one. Our MCAT prep guides cover the rest of your plan!
Every MCAT test form measures the same basic concepts and skills, according to the AAMC. Those are what you’re building, whichever form you get!
How to Answer an MCAT Question You’ve Never Seen
Start every MCAT question, new or familiar, with these two habits.
- Read and rephrase. After you read the question, pause and put it in your own words. What is it asking you to find?
- Predict or eliminate. Work out your own answer and pick the choice closest to it, or cross off wrong choices one at a time. Try both and keep the one that works for you!
Two more help once you’re in the answer choices, and they come up a lot in CARS.
When you’re down to two, leave the passage and the four choices alone for a moment. Your reworded question gives you something to test both choices against 🙂
In our 6-Week Live MCAT Accelerator, we practice live passages in every section and work on the AAMC-style passage logic behind these habits.
Do MCAT Questions Repeat? Quick Answers
Does the AAMC reuse a whole MCAT test?
The AAMC hasn’t said. It describes the exam as a set of test forms, each with different specific questions, and it doesn’t publish how often a form is given.
Will I see the same questions if I retake the MCAT?
The AAMC hasn’t said, so plan your retake around new questions. Our MCAT retake guide helps you decide what to change, and our guide to MCAT attempt limits covers how many times you can test.
Are MCAT questions the same in the US and Canada?
The AAMC runs one MCAT, with the same sections, timing and score scale wherever you test. It doesn’t publish which form any test center gets.
Is the MCAT multiple choice?
Yes! All four sections are multiple choice, and there’s no penalty for guessing.
Does the MCAT change every year?
The AAMC’s policy guide, The MCAT Essentials, can change from year to year, and returning test takers have to read the current version. For 2027, the AAMC lists the four sections and 230 questions in the table above.
Final Thoughts on Whether MCAT Questions Repeat
Wondering about repeats makes sense when so much rides on one test day. The AAMC’s answer points you to the skills every form measures, and you can start building those today!
If you’d like mentors beside you, our 6-Week Live MCAT Accelerator works live passages in every section with you.
If the cohort dates don’t line up, 1:1 MCAT tutoring pairs you with a 515+ scorer. Either way, we’d love to help you reach your MCAT score goal and, after that, your med-school dream. You’ve got this 🙂
