Other than following the tips we outlined above, such as borrowing only what you need, choosing schools with cheaper medical school tuition and fees, and living within your means, another thing you can do is pay down any existing debt before you start medical school.
Debt has a way of accumulating, and trying to juggle undergraduate debt in addition to medical school debt will be difficult. Instead, focus on paying down that debt in advance. Another good option for reducing your debt is to work throughout medical school.
If you find your course load too heavy to work during the actual school year, try to work part-time over the summer or during breaks to help you bank some extra money.
