in the Medical School Admissions Requirements(MSAR), which has a summary in a standardized two-page format for each allopathic medical school, at the top of the right-hand page, immediately under the “Premedical Coursework” heading is this:
On-line course accepted in fulfillment of prerequisites: followed with a yes, no or case-by-case basis
Please note while these represent the policy of each school, the competitiveness of online courses versus traditional classroom is not evaluated. Please keep this in mind when considering online courses.
Also keep in mind that nontraditional does imply atypical. Online courses, as well as all other factors should be considered in the pattern of motivation, commitment, and achievement that your application represents to an admission committee.
