I believe they have an online course to prepare for the exam, they are very pricey so just practicing is enough for some people. I bought Kaplan, Dr. Collins and PCAT Destroyer but felt that Dr. Collins was the most effective. I took the exam for the first time in November and I give you some pointers. One thing I regret the most is re-learning the content when you can just study smart. Kaplan is amazing for Biology but is disappointing when it came to math, reading comprehension, and chemistry. For Chemistry, I would use Dr. Collins. If you do not know your content then I would just open an Chemistry textbook for clarity but if you do not have time just go with Dr. Collins. For Math, I used princeton review to go over some math concepts. I do realize it is VERY old but I thought it was helpful in brushing on calculus. I didn't have any problems with Calculus on the PCAT only because in college I had to take up to Calculus III and that helped prepared me. I did have some issues with timing myself on the math section especially. Nonetheless, Princeton, Dr. Collins and the Pearson practice exams were really good for the math section. For CR, just honestly practice as much from Kaplan and their GRE books. I use the Manhattan book just to get more practice. As for the essay, the study guide shows you what is an excellent essay. I bought this book call Master the PCAT Essay and it really helped me structure my essay and I would suggest it especially if you are lost on where to start.
I'm also taking the January 2017 PCAT exam so we all got this!! I am going to take the Kaplan practice exam and see if the questions are similar. I believe we all can do this. Just study smart. If you have one month left, just practice off exams.
