I've been taking the Kaplan course for the past month or so. I received a 19 on my Diagnostic (which I'm not too worried about because I've heard those are designed to scare, and I simply didn't remember simple equations). While I study with a fair amount of intensity, I find that the Kaplan passages at the end of each lesson are still very difficult. I'm able to get about half of the questions right. I would appreciate feedback from anyone who has taken the actual MCAT after taking the Kaplan course and can give me a good comparison to not only the Kaplan diagnostic and actual MCAT, but the short Kaplan practice passages and the actual full-length Kaplan tests and the actual MCAT. Also, to anyone else currently enrolled in a Kaplan course, let me know your feelings on Kaplan material.
