I took OChem I and II 3 years ago and didn't realize how little of it stuck with me. Examkrackers just isn't cutting it for OChem content review...I read the EK chapter and watched all the khan academy videos regarding stereochemistry and whatnot, and still missed about half the questions in the 30-minute lecture exam. Reading the answer explanations, it felt like I was reading a different language. Does anybody know of any resources for OChem that goes a little more in-depth and has more practice, but is still succinct enough to do in a reasonable amount of time?
