The MCAT tests medical students to-be on their knowledge of problem solving, critical thinking, and knowledge of natural, behavioral, and social sciences. The vast majority of medical schools require MCAT scores as a part of the admission process.


The entire exam consists of multiple-choice questions. The structure of the MCAT changed in April, 2015, and the test is now scored in four multiple-choice sections.

Total Testing Time: 7 hours and 30 minutes
Time per Block: 95 minutes
Tutorial (optional): 10 minutes
Break Time Allotted: 50 minutes (including 30 minutes optional lunch break)
Total Multiple Choice Questions: 230

Content Areas

The four sections of the MCAT are:

Biological and Biochemical Foundations of Living Systems (59 questions)
Chemical and Physical Foundations of Biological Systems (59 questions)
Psychological, Social, and Biological Foundations of Behavior (59 questions)
Critical Analysis and Reasoning Skills (53 questions)

Unlike many multiple-choice exams, the MCAT does not penalize wrong answers. Only correct answers are scored. According to the AAMC, “even if you are unsure of the correct answer to a question, you should make your best guess.”


Raw scores from each of the individual sections mentioned above are converted to scaled scores that range from 118 to 132. Raw scores are converted to scaled scores to account for a potential variation in the difficulty level of questions. Two equally capable students may have slightly different raw scores, but the same scaled scores.

According to the AAMC, the mean score is 499.6 and the standard deviation is 10.4.
