Medical school is expensive.
Unless you are very fortunate, you should anticipate going deeply into debt. Consider your debt the equivalent of a home mortgage or a small business loan. Most loans are administered by the medical schools and they will work closely with you after you have been accepted. This includes all tuition costs, money for books and supplies, and a monthly stipend. In turn, the awardees have the oligation to serve a number of years on active duty as a physician.
