I didn't really have the money or the time to take an actual Kaplan or Princeton Review course so a friend of mine gave me a ton of PDFs of old Kaplan practice tests from 2003. They are super long, 77 questions for PS and BS and 60 questions for verbal. They are also so difficult to do, so I am wondering if its even worth going through all of them. Has anyone taken these tests before? Do they help for the actual MCAT? Or am I just wasting my time..
