I've been harping this to people but seriously buy the practice exam for the PCAT:

The truth is many of these study guides' organic section review is pathetic. Seeing the actual exam and what type of questions will be asked is the key. When I took the PCAT, I only had Kaplan's study guide under my belt and when I took the chem section, I was like what is going on? Definitely had stuff I was not expecting but I do have an M.S. in organic chemistry so I managed to do well.
Ultimately, what I'm trying to say is that if I didn't have an ochem background, I was really
screwed. So my best advice is to keep looking at problems. You will have a gauge of what you really need to review in regard to ochem and old notes will probably be more than enough to prepare you all. Good luck!
