The MCAT test evaluates the scientific knowledge, critical thinking, and reasoning skills that medical schools expect from incoming students. If you're wondering what is on the MCAT exam? Why does it matter? This guide covers everything from the MCAT format and MCAT exam length to scoring and registration.
What Does MCAT Stand For?
MCAT stands for Medical College Admission Test. The exam has existed in some form since 1928, making it one of the oldest standardized tests in the country. The current version, the format most students know today, was redesigned and launched in April 2015 to better reflect modern medical education, with an emphasis on applying knowledge rather than simple fact recall. The MCAT exam is administered exclusively through the AAMC and tested at Pearson VUE centers nationwide.
MCAT Exam Format: Sections, Questions, and Timing
The MCAT format consists of four multiple-choice sections administered in a fixed order. Here is the complete MCAT exam breakdown.
They are:
- Biological and Biochemical Foundations of Living Systems
- Chemical and Physical Foundations of Biological Systems
- Psychological, Social, and Biological Foundations of Behavior
- Critical Analysis and Reasoning Skills (CARS)
How Long Is the MCAT?
The total MCAT exam length from check-in to dismissal is approximately 7 hours and 30 minutes. The actual MCAT test duration (questions only) is 6 hours and 15 minutes. Each student is allotted one 30-minute mid-exam break and two 10-minute optional breaks. Unused breaks do not carry over to the next section. Each of the four exam sections is tested for 90 to 95 minutes, making the total testing time about 375 minutes (6.25 hours). The MCAT test length and MCAT exam duration have remained unchanged since the 2015 redesign.
How Many Questions Are on the MCAT?
There are 53 to 59 questions per MCAT section, coming in the form of passage-based and discrete (standalone) questions. Altogether, there are 230 questions on the MCAT. This makes building your test-taking endurance a vital piece of your exam preparation.
Why the MCAT Matters
A strong MCAT score is one of the most important components of a competitive medical school application. Nearly all U.S. medical schools and many Canadian programs use your MCAT test results to assess your readiness for the rigors of medical education. Medical schools consider the MCAT alongside your GPA, extracurriculars, personal statement, and interviews when making admissions decisions.
How Is the MCAT Scored?
Each of the four MCAT test sections is scored on a scale of 118 to 132, for a total score range of 472 to 528. The midpoint, a score of 500 represents average performance. Most competitive applicants applying to U.S. medical school programs aim for a 511 score or higher, which places them near or above the median for matriculants at many schools. Scores are released approximately 30 to 35 days after your exam date by 5 PM ET. For a detailed breakdown of what your score means and how medical schools evaluate it, see our MCAT scoring guide.
MCAT Registration and Test Dates
You can register for the MCAT test through the official AAMC website. The MCAT is administered between January and September at certified testing centers. Early registration is recommended to secure your preferred date and location.
When Do You Take the MCAT?
MCAT test dates are updated each year, and you should register for the MCAT as soon as you know your preferred testing date. Most students take the MCAT in their junior or senior year of college after having completed introductory science, psychology, and sociology courses. Most students take the exam in the spring or summer one year before applying to medical school.
Give yourself 3–6 months to prepare. Most students score their best after 300+ hours of MCAT test prep.
