There were Calculus problems on the October 2006 PCAT, but there were fewer than I originally anticipated. I had my calculus course five years before I took the PCAT, and I really didn't review the subject hard. There were a couple of problems that I didn't know how to solve. But like I said, I was surprised that there wasn't more Calculus. However, I believe I read somewhere on this board that the PCAT will slant towards more calculus in the future, so I am unsure about the content of the test when you will take it.
For what it's worth, I got a 96 on the math section, so you can do okay if you at least buy a calculus review book and learn the basic concepts.
If you have had pre-cal in high school you should be fine. I took the Jan 07 PCAT barely studied any math cuz to me math has always been the easier subjects (i was more freakiing out about bio). Turned out I had the most difficulty with math on the actual test bc I dont remember any of the elementary stuff (afterall, i havent done math in awhile). Surprisingly I got a 97 on math which is my highest score!!! I dont think Kaplan has a good math section tho, I'd probably just get a pre-cal textbook from highschool or in da library and flip through it quickly. Nothing u cannot do without a calculator!
