i've been taking several post-bacc classes at UNC over the past year and have been quite happy with the flexibility and opportunities that the program has given me. unc has a loooooooooooootttttt of pre-med students though, so the classes are big and competitive.
for continuing ed/part time studies, they only let you take a max of 9 hours though, per semester. that's basically two classes and one lab. if you want to take more in a given semester, you have to write a letter of appeal. i did that once, and it was accepted.
i've taken a smattering of stuff everything from physics and chemistry to pathology classes.
Go Heels!
