Hey! I've also been thinking about how much time is needed to study for the PCAT too with all the talk about it recently. I wonder if I should purchase Kaplan's study book now even though I'm not planning to take the PCAT until 2 years later. Or should I just wait until I am ready to take the PCAT?
Panda103 ~ I found Kaplan to be helpful with the Biology section as it is quite in depth. The math section is now mostly obsolete since it now focuses on CALCULUS and PRECALCULUS. It is good for a quick brush up on some other concepts that precalc and calc are built upon. I found the chemistry section to be waaaay too in-depth. The practice problems at the end of the chapter don't take into consideration the fact that you have a TIME LIMIT and NO CALCULATOR. You're better off buying Cliff's quick-review chemistry! ($9.99!) I found it to be MUCH more helpful. As far as the reading comprehension and verbal, Kaplan is a pretty good guide!!!
Hope this helps and good luck studying! DON'T CRAM and try to give yourself a week or two at the very least to review!
