Yes!! But I'm retaking the exam on Wednesday!! I used all the wrong material the first time I took my exam and was not prepared for it the way I am now. Even though I did poorly the first time i took it, I feel like I can give advice from my mistakes.
Yes, the princeton review book was horrible. I liked the way it taught the material, but it's just waaaaay too into depth for anything that will be asked on the actual PCAT. The supplemental information online that comes with the book is much more difficult than anything the PCAT will expect of you, I guess it's good practice, but there's no way anyone can finish that material in the allotted time given for each section.
Collins material is concise and straight to the point for what will be asked. Even though some of the material is old in Dr. Collins, the general idea is there for what needs to be known for the exam, it cuts all the nonsense out.
Books like Kaplan and TPR etc are good for more understanding if you don't understand something from Collins. Just go through the pearson vue exams THOROUGHLY (meaning, read the answers/explanations for even the questions you got correct) and I think we should be fine
