Biology was more microbiology than I anticipated but didn't have many plant questions. I did see one or two plant questions but they were very basic. The big thing for biology is knowing diseases so you should know how basic medicines work in general. A question might ask about antibiotics and list multiple organisms and ask which are or aren't affected.
Chemistry was actually pretty different than I anticipated. I used Kaplan and expected mostly math but to my surprise there was a ton of conceptual questions, in addition to organic chemistry and biochemistry. The biochemistry seemed to be basic, basically what you would see out of the first couple chapters of a biochemistry book.
I used Kaplan PCAT 2012-13 for biology and general chemistry. Since I have never taken organic chemistry or biochemistry, I used organic chemistry as a second language I, up to SN1/SN2 reactions, and read the first couple chapters of Lehinger Principles of Biochemistry.
My biology score was 97th percentile and chemistry was 93rd percentile; keep in mind, I just finished my first year of pre-pharmacy, so if I can do it, you can too.
You certainly don't need to go out and buy $300+ worth of Dr. Collins supplies to finish strong. You would do fine with free online ebooks and the $50 Kaplan book. The Pearson practice exams did have the new material labeled but what it lists as biochemistry is not what's on the actual exam. Expect reactions and amino acid structures. Check your general chemistry book for amino acid structures, I know mine has them.
As for the other sections, most of them are what would be expected. The quantitative has quite a bit of trigonometric identities embedded in most problems and the reading comprehension readings all seem to be about 6/7 paragraphs.
Good luck!
