I was looking at some post bacc programs online because I want to improve my science gpa. The problem is, alot of them are designed for people who have never taken science classes (which I have taken alot of) and take 2-3 years to complete. So to improve my chances at d-school, should I enroll in a masters program, take graduate classes, or take more undergrad bio classes ?? I really do not want to retake my prereqs because i dont think they are that bad,, mostly's Bs and a few Cs... but I know I need to do something. Also, if you know any good programs/schools in the nyc area, please let me know. thanks.
