Im taking the PCAT in july and have been studying since April 15. Study from 10am-8pm with 1 or 2 hours in there to eat. Using Dr. collins 2017 self study, cliffsnotes ap bio, all of chadsvideos chem videos, and kaplan for math, and whatever free pcat study sources i can find online.
I have to say, i really don't like the dr. collins review. The guides just assume you already know everything and am just reminding you of small things here and there to keep in mind. Also in the bio review there are many times where it says something like, "refer to page 18 of the bio review book..." but you can't really do that since you are reading this off the only bio review packet thats given. The rest are just practice exams. Use dr. collins study guide for practice only. Don't rely on this to actually study if you forgot a lot of things.
