PRIYA:
I posted an answer for your other question, but here is my other response. I took Kaplan for the April 2002 MCAT. Considering how bad my diag. was, I did go up 8 points and did well on my WS. I spent 6 days a week, and 6-7 hours a day at the test center. I worked until I could work no more. I got to 90% of the material. As I said, it did pay off by my 8 point score improvement - I went up 3-4 points in BS and VR but only 1 point in PS. I thought of retaking the course and paying the $400, but I want my refund now.
I would look into other reputed MCAT prep books, For the August MCAT, I am using only EXAMKRACKERS. You can get the books at any Barnes and Nobles. I think I will vomit if I see anymore Kaplan material. GOOD LUCK
