The Medical College Admission Test (MCAT), developed and administered by the AAMC, is a standardized, multiple-choice examination created to help medical school admissions offices assess your problem solving, critical thinking, and knowledge of natural, behavioral, and social science concepts and principles prerequisite to the study of medicine. 

The exams are offered from January and March through September at hundreds of test sites in the United States, Canada, and around the world.
