I am just finished UCONN's post-bacc this past spring and start med school there in 4 days. Feel free to PM me if you have questions about the program. I had a great experience and recommend it highly.
I will be doing a post-bac program at Penn this Fall. They are two types of programs, one is called Pre-Health program, targets those who have not done/completed their pre-med courses. The other program is Speacial Science Program for students who have taken all the Bio, Chem, O-Chem, & Physics but needed to take upper division science classes to strengthen their GPAs. You need to take a minimum of 6 courses to complete either of the program and the advisor there will write you a letter of recommendation when you apply to med schools. Good luck!
