Depends on how much time exists between undergrad and med/grad school. If you are going right on to med school with no lag year in between, they can be deferred until you finish med school. However, if there will be more than 6 months between completion of undergrad and med school, and you are not enrolled at least half-time in another program, you will have to begin making payments after the grace period (6 months) expires. Once you begin school again, these can go back into deferment.
