How long is the MCAT?
The MCAT takes about 7 hours and 30 minutes of seated time, according to the AAMC. Of that, 6 hours and 15 minutes is testing, spread over four sections of 90 to 95 minutes each. The rest is optional breaks, a short tutorial and an end-of-day survey. Check-in at the test center comes on top, so plan for a full day.
The MCAT has four sections and 230 questions. Three science sections have 59 questions in 95 minutes each: Chemical and Physical Foundations of Biological Systems, Biological and Biochemical Foundations of Living Systems, and Psychological, Social, and Biological Foundations of Behavior. Critical Analysis and Reasoning Skills, or CARS, has 53 questions in 90 minutes. Each section is scored from 118 to 132, for a total of 472 to 528.
The day runs in a fixed order: a 4-minute test-day certification, an optional 10-minute tutorial, section 1, an optional 10-minute break, section 2, an optional 30-minute mid-exam break, section 3, another optional 10-minute break, section 4, then a 3-minute void question and an optional 5-minute survey. The AAMC's 7.5 hours do not include check-in when you arrive.
That works out to roughly 97 seconds per science question and about 100 seconds per CARS question, almost all of them tied to passages. The hard part is less the content of any one section than keeping your focus for the fourth one. That is why full-length practice under real timing matters. Your score arrives about 30 to 35 days after test day.
| Section | Questions | Time |
|---|---|---|
| Chemical and Physical Foundations of Biological Systems | 59 | 95 min |
| Critical Analysis and Reasoning Skills (CARS) | 53 | 90 min |
| Biological and Biochemical Foundations of Living Systems | 59 | 95 min |
| Psychological, Social, and Biological Foundations of Behavior | 59 | 95 min |
| Total testing time | 230 | 6 h 15 min |
| Total seated time with optional breaks | - | About 7 h 30 min |
- 1Take one full-length practice exam early, with the real breaks: 10, 30 and 10 minutes.
- 2Note the section where your accuracy drops. That shows where stamina, not knowledge, costs you points.
- 3Train in timed blocks: 95 minutes for a science section, 90 minutes for CARS.
- 4Do a few CARS passages most days, since reading speed builds slowly.
- 5Every one to two weeks, take a full-length exam at your real start time.
- 6In the last week, review your missed questions, keep sessions shorter and sleep well before test day.
