What's on the MCAT?
Four sections, 230 questions, about 7.5 hours at the test center. Here is what each section covers, how long it runs, and how the scoring works, in plain English.
The four sections
Every test day runs the same order. The three science sections mix passage groups with standalone questions; in CARS, every question belongs to a passage.
C/P · 59 questions · 95 minutes
General chemistry, organic chemistry, physics, and biochemistry, asked through how living systems behave: gas exchange, circulation, lab technique.
CARS · 53 questions · 90 minutes
Passages from the humanities and social sciences, with questions about what the author claims, implies, and assumes. No outside facts are tested.
B/B · 59 questions · 95 minutes
Biology and biochemistry first, with general and organic chemistry in supporting roles: cells, organ systems, metabolism, and the molecules that run them.
P/S · 59 questions · 95 minutes
Psychology, sociology, and the biology behind behavior: perception, learning, memory, identity, social structures, and health.
CARS works differently from the other three, so it has its own practice guide: reasoning you can train, not content you can cram.
How the day breaks down
Testing time is 6 hours 15 minutes. With breaks and check-in it becomes a full day, so treat stamina as part of your preparation.
| Block | Questions | Time |
|---|---|---|
| Chemical and Physical FoundationsC/P | 59 questions | 95 min |
| Break (optional) | 10 min | |
| Critical Analysis and Reasoning SkillsCARS | 53 questions | 90 min |
| Mid-exam break (optional) | 30 min | |
| Biological and Biochemical FoundationsB/B | 59 questions | 95 min |
| Break (optional) | 10 min | |
| Psychological, Social, and Biological Foundations of BehaviorP/S | 59 questions | 95 min |
Breaks are optional. Take them: the back half of the day is where pacing quietly falls apart.
Scoring: 118 to 132, no penalty for guessing
Each section is scaled from 118 to 132, and the four add up to a total from 472 to 528. A 500 sits near the middle of the scale. Scaling smooths out the small difficulty differences between test forms, so no test date carries an edge.
There is no penalty for a wrong answer: a wrong guess costs nothing more than a blank, and a lucky one pays. Answer every question, flag the ones you want to revisit, and keep moving.
Your report also shows a percentile, which is where your total falls among everyone who tested. Schools read the percentile alongside the number. The MCAT reports a percentile, never a rank.
Common questions
How long is the MCAT?
Testing time is 6 hours 15 minutes across the four sections. Add the optional breaks, check-in, a short tutorial, and the end-of-day survey, and the full appointment runs about 7.5 hours.
What order do the sections come in?
Always the same: Chemical and Physical Foundations first, then CARS, then Biological and Biochemical Foundations, then Psychological, Social, and Biological Foundations of Behavior. You can take a 10-minute break after the first and third sections and a 30-minute break in the middle.
Is there a penalty for wrong answers?
No. Your scaled score counts only what you got right, so a wrong guess costs nothing more than a blank. Answer every question, even the ones you have to guess.
What counts as a good MCAT score?
The total runs 472 to 528 and 500 sits near the middle. What counts as competitive depends on the schools on your list, so read your percentile alongside the number: it shows where you stand among everyone who tested.
