If you have not completed your pre-med requirements during undergrad, you will need to complete them at a Post-Baccalaureate program. You can learn more about them at the link below.
Frankly, these are pretty expensive considering what you are getting, but if you didn’t finish your pre-med reqs in college, it is probably your only alternative.
My company has a couple of Med School Counselors with Post-Baccalaureate Experience – they have recommended Bryn Mawr and Harvard’s program in the past. Then it’s MCAT and applications.
So, the short answer is yes, absolutely, but it will not be cheap. Post-Bacc programs are quite expensive, and in my experience do not offer nearly as much financial aid as the other programs at those schools.
Once in med school, you will need to meet certain requirements if you want to be a particular type of surgeon (e.g., doing well on Step 1 boards).
Hope that helps!
