I have just started studying for the MCAT, I started with Physics and I have been going through TPR and then going through EK to see if I got it all from TPR or if I missed something. Now I haven't had Physics in 4 years so that is prob. a huge factor, but I cant seem to get many of the practice problems right in either EK or TPR. I dont know if I need to take a prep class, or what??!!!! I dont have much money and that is why I was trying to study with the books instead of the in-class courses but I dont know what to do? I have heard that if you get the Audio Osmosis from EK you have access to online question/answer type help, is this true? Does it really help that much? Any suggestions about what I should do?
