I take my test 8/23. I have a lot of practice tests (including 4 AAMC) to take. I've read through: BR Physics and Chem, TPR Chem, Physics, Organic, and most of EK Bio, Chem, and Physics. I've also done a lot of the TBR passages and other practice tests. And of course I wouldn't say I have a perfect understanding of them all but I've gained a fairly good understanding. Still, reading through things I've already read over may not be the best course for me. At this point, would it be worth $40 to go through Chad's videos?
