IMHO, the only post-bacc programs worth attending are those that will guarantee you a spot in medical school if you perform above a certain level. These are post-bacc programs with "affiliations" or "linkages". I don't believe Drexel has any such arrangement. However, Bryn Mawr College does. See http://services.aamc.org/postbac/ for a list of programs.
I got accepted to Drexels post-bac program last year. My app was forwarded when they denied my med school app. I decided not to go mainly because it seemed like alot of money and it wasn't focused on what I felt my weaknesses are/were.
Sorry can't help more.
