I used the Kaplan book to study for the PCAT. I don't really recommend it, though, because, as I discovered just before the test, they take most of the MCAT book minus physics and change all the Ms to Ps. Needless to say, after I took the test, I realized the Kaplan book had nothing to do with the PCAT with or without the new changes. Having said that, it did help me to be studying at all and to be repeatedly refreshing my memory with stuff I hadn't dealt with since freshman year or even high school. So, even though studying the wrong stuff didn't help, keeping my mind on its toes did. Hopefully other people will have much more specific advice than that. :-\
When I took the PCAT, I definitely didn't know everything. I've never had microbiology, prob & stats...I mean, let's be honest, I knew almost nothing in the math section. So that was really, really scary...It really changed my mood during the test, but luckily I got wrapped up in the chem section that turned out be easier than I expected (less gen chem!), so I forgot about it. Somehow it ended up working out, much to my surprise, so I guess it was especially good that I did not dwell on it too much.
I studied a little less than a month before the test. Most of it was because I thought I needed refreshers in basic "bio" (like ecology and animal behavior, which weren't on the test) and gen chem (not half as heavily tested as in the book), which I loathed when I took them. Knowing what I know now, for studying, I'd say spend time on the things you yourself would guess are important (the fact that I even looked at the section on plants astounds me), like physiology and o chem. For reading, definitely do as many passages as you can find; it really helped me pace myself and in general comforted me that I could read the whole passage without running out of time. I think questions in general are the key. Lots of review questions and practice tests helped me.
Finally, I made flashcards, but it's funny because I didn't use them probably half as much as most people would. They were basically just ways for me to take notes. What I found myself doing more often was when waiting for buses or standing in the shower, I would try to recall as much as I could about X, Y, or Z and then if I had some big gap in my memory, I would go back and look at that when I studied. I would also do and redo problems until I had finally learned the process, although had I known better, I would have just consult a stats textbook D:
I hope that helps! Good luck!
