About the MCAT
The MCAT (Medical College Admission Test) is a standardized examination administered by the AAMC, required for admission to MD-granting medical schools in the US and Canada. It is one of the most comprehensive standardized tests in existence — 7.5 hours of testing across four sections. A strong MCAT score is one of the most important factors in medical school admissions. The MCAT can be taken multiple times but is limited to 3 attempts per year and 7 lifetime attempts.
