Anyone joined the program their sophomore, junior or senior year? How long did it take to complete?
The med school pre-requisite coursework takes about two years to complete, because some of the classes must be taken in sequence. You work it in around your other classes, although depending on your major, there could be some overlap.
Becoming pre-med in your senior year, without having a major where you’ve already taken a decent number of the pre-med classes, should set you back in terms of graduating on time.
