Take the Dr. Collins course!! I didn't have the luxury of being able to take the Dr. Collins course because its only offered in Florida, but I bought the Dr. Collins packet and studied off of there and referred to the Kaplan book (about 20-30 bucks) and the McGraw Hill PCAT book (super cheap and really good for bio and chem), I felt really prepared. Dr. Collins has a lot of practice tests and lets you practice with questions that are on the pcat or were on the pcat at some point. Kaplan really is far too in depth and misses a lot of key topics like microbiology. Dr. Collins targets the topics you need to learn! If you want a really great score, go for Dr. Collins and you wont regret it. But also buy a Kaplan PCAT and McGraw Hill book, they are useful get a little more knowledge.
