Hey, I have AP Chem right now, and I think I'm doing fairly well. I have the princeton review and an old 5 steps book. I also have flash cards that generally review for each section. What I want to know is, what are the important areas and concepts that I should review most for? Is there more on stuff like equilibrium, enthalpy, or anything like that? Also, how hard would it be to get a 5? How hard would I have to work and study with the books to do well?
