One more thing: When I was thinking of applying to the BU MAMS program a few years ago, I met with its program director, Dr. Offner. She was really nice and open to meeting with me right away. She was also a straight-shooter and told me that I should not apply to the program at that point because there were other areas in my application that needed to be fixed before even a post bacc program could help me. Both my father (who had accompanied me to the meeting) and I appreciated her honesty. She seemed to genuinely care that the students that were admitted into the SMP actually succeeded in getting into medical school (as opposed to just making money off of desperate premeds). On our way out, we noticed that the office of the Dean of Admissions for BU med school was right next to her office. It made me think that any student who did really well in the post bacc program and made a good impression on Dr. Offner might have a leg up while applying to BU med school if she had such easy access to the Dean.
I don't know if things are still the same at BU, nor do I know anything about Georgetown. But it's something to explore if you are dropping thousands of dollars on an SMP.
