Hey guys! Sorry if I'm late but I took my PCAT in September and here are my prelim scores:
Biology: 63
Chemistry: 98
RC: 87
Quantitative: 99
Overall: 97th
I studied for about a month and a half for it but I did spend quite a lot of different forms of study guides and would like to share some advice.
I personally felt like Princeton Review was the best book for chemistry. Honestly, the PCAT focused heavily on basic general chemistry and basic basic organic chemistry (E1, E2, Sn1, Sn2 reactions). Princeton Review explains the chemical principles really well and covers basically all of the gen chem/ochem topics. The only thing that it lacks in is biochem (but the PCAT doesn't really emphasize that). I thought Kaplan was the best for bio because it's so detailed but the rest was average. It really explained very little in chemistry and the quantitative reasoning too easy compared to the real thing. I didn't focus that much on Bio and took general biology almost two years ago (which is why I struggled).
As for study prep/test taking, BUY THE PEARSON TESTS. They're $90 for three multiple choice tests and they, in my opinion, were very similar in terms of both difficulty and the types of questions asked on the PCAT. Do those in a actual test format and you will be fine. The Kaplan tests were much more difficult in both the biology and chemistry sections (especially the reading parts) and they focused too much on random organic chemistry reactions and anatomy/physiology. Also, a lot of universities (Penn State, University of Kentucky, University of Wisconsin, Texas AM) have general chemistry exams you can take online as well as powerpoint lectures from professors for review if you're looking for something free. Just type in General Chemistry Past Exams and say for instance Penn State and you can get a lot of past exams. University of Wisconsin also has organic chemistry tests available online for review.
You may have heard about things like PCAT Cracker and Crack the PCAT. Well I bought both and they both really suck. The questions are ridiculously hard and the explanations are even worse. They often times use the same explanations for different questions and the video explanations often times don't match up with the questions. For instance, if asked a question about acidity, the explanation you'll get is basically "we know it is an acid because it is an acid". Also, they advertise things like 10 practice tests or 2000 problems but often times, they're the same problems over and over again. So in reality, you get like 100 problems per section. In addition, the programs often times glitch and they calculate your scores wrong.
When I took practice tests on Kaplan, I scored in the mid 80th most of the time, but as you can see, I scored in the high 90s (again not to brag) on the actual thing. Again, Pearson's practice tests are the best, the only problem is that there are only 3 you can choose from.
I hope this helps! I'll definitely be posting more!
Thanks!
