How Long Is the MCAT^®?

The MCAT^® takes about 7 and a half hours of seated time, and 6 hours and 15 minutes of that is the four test sections. Add the 30-minute check-in before your start time, and plan to spend most of a day at the testing center.

How the Day Breaks Down

The four sections run 95, 90, 95 and 95 minutes, in a fixed order, with three optional breaks between them: 10 minutes, then 30, then 10. If you take every break in full, the clock looks like this.

That's 7 hours and 5 minutes from the first question to the last. The rest of the roughly 7.5 hours of seated time comes before and after. Before Chem/Phys, you accept the exam's certification statement and get an optional 10-minute tutorial on the testing interface. After Psych/Soc, you decide whether to score or void the exam, and then there's a short optional survey.

The four sections themselves add up to 375 minutes of testing across 230 questions.

What the Break Rules Say

The AAMC's rules on breaks are stricter than most people expect.

• Breaks are optional. You can skip any of the three, but unused break time doesn't carry over. If you come back early, the next section starts as soon as you sit down.
• Going over costs you. Any time past the break limit may come out of the next section, and running long can also cost you the ability to void the exam.
• The clock doesn't stop for an unscheduled break. You can leave mid-section to use the restroom, but your section timer keeps running.
• Food stays at the center. You can't leave the building to get food or have it delivered, so pack what you'll eat and keep it in your locker.

When to Get There

The AAMC tells you to arrive 30 minutes before your start time, which is when staff begin checking people in. Check-in includes showing your ID, having your photo taken and a palm scan, and stowing your things in a locker.

Count it all up, from arrival to walking out, and you're looking at about 8 hours, before the drive. Block off the day.

How to Get Ready for the Length

The length is its own challenge, separate from the content. A few habits help.

• Take full-lengths on the real schedule. Same start time, same break lengths, same snacks. The full-length review guide covers what to do with the results.
• Use the 30-minute break to eat. It comes after CARS, more than three hours in. Bring something you've already tested on a practice day.
• Plan your caffeine. If you drink coffee, time it the way you would on a practice day. The stimulants article covers caffeine on test day.
• Practice the last section tired. Psych/Soc starts five and a half hours in. Your practice tests are the only way to find out how your focus holds up at that point.

If you test with approved accommodations, such as extra time or extra breaks, your schedule will run longer than this one. And once it's over, the score release guide covers the month-long wait for your result, which you can look up in the PurpleCAT MCAT score guide when it arrives.
