Sooooo its been a while since I've taken gen chem/bio any advice on the best way to review the important info before I start TPR in january?

ExamKrackers

examkrackers if you still remember the concepts. EK will only freshen your original knowledge, it can't build the foundation.

your textbooks if not.

you're starting a review course in january, that should do fine. Buy EK, and it will actually help you out though
