MCAT Exam Format: Sections, Question Counts, Timing and Breaks

The MCAT has four sections, 230 scored questions and about 6 hours 15 minutes of testing, with breaks and administrative screens bringing the day to roughly 7.5 hours. Confirm current details on the AAMC site before your test date, since logistics can change.

The four sections

Total: 230 questions and 375 minutes of testing. The sections always run in this order. Every question is multiple choice with four options, and there is no penalty for a wrong answer, so never leave one blank.

Breaks

After the tutorial and agreement screens, you test with a 10-minute break after the first section, a 30-minute meal break after the second, and another 10-minute break after the third. Time spent on breaks cannot be banked, and the clock keeps moving during them.

Scoring

Each section is scored 118 to 132, with 125 about the midpoint. Four sections add to 472 to 528, with 500 near the median. Scores are scaled to account for form difficulty, which is why raw percent correct varies by test. The score calculator note shows how to estimate.

Content by section

• Chem/Phys: general chemistry, physics, organic chemistry, and biochemistry.
• CARS: humanities and social science passages, tested without outside content.
• Bio/Biochem: biology, biochemistry, with organic and general chemistry.
• Psych/Soc: psychology, sociology and biology, and research methods.

Pacing worked example

For a 95-minute section with 59 questions, you have about 96 seconds a question. A passage of 5 questions and a roughly 600-word text gets about 8 minutes: 2 minutes reading and 6 minutes for the questions. Flag any question that goes beyond 2 minutes, answer it with your best guess, and return if time remains. For CARS, 9 passages in 90 minutes is 10 minutes a passage.

Common traps

• Practicing in short blocks only. Stamina matters. Take full-length exams.
• Skipping the break food plan. Practice the same break schedule on test-like days.
• Leaving blanks. Unanswered questions are marked wrong.
• Assuming section order can change. It cannot.

One-minute recap

Four sections: Chem/Phys 59 questions in 95 minutes, CARS 53 in 90, Bio/Biochem 59 in 95, Psych/Soc 59 in 95. 230 questions, 118 to 132 per section, 472 to 528 total. Breaks of 10, 30, 10 minutes. No guessing penalty.
