I used Kaplan, wasn't that helpful (only strategies). I browsed through my gen bio book. I just took molec bio before the PCAT so alot of that stuff I didn't bother with. I focused on A&P stuff in the bio book because I had not taken A&P yet. Ended up I really didn't need it. For math, I just did Kaplan and some calculus from my book. I did up to calc II, so it was just to refresh quickly. Didn't prepare for reading or verbal (just Kaplan strategies). I rushed through those sections thinking I would be running out of time, only to find I finished those sections early....should have slowed down. Chemistry was easy since I was a biochem major, didn't study too much, just some of the ancient gen chem stuff that isn't important after you are done with gen chem. Found the PCAT to be extremely general in the chemistry department.
