Hey, Im not sure where you live in chicago, but my girlfriend went to a PCAT prep course at midwestern university (they have two a year) and liked it. It was around $300 or so. She also got the name of a biology prof, at a community college in S. Holland, that runs the pre-pharm club there. He is awsome from everything I have heard. When she gets home I will get his name and post it for you.
Also, what specifically do you need help with? I took the PCAT and got a 94 so let me know if I can help you in any way!
