MCAT Data and Research

Research results and additional data will be added to this page as information is collected on the new MCAT exam, which launched in April 2015.


The below resources include data on the three multiple-choice sections on the old exam (Biological Sciences, Physical Sciences, and Verbal Reasoning) as well as the Writing Sample section, which was administered as part of the MCAT exam from 1991 to 2012. The Writing Sample section was removed from the MCAT exam beginning in 2013 in order to allow time for the administration of a Trial Section to inform the development of new test questions for the new MCAT exam.
