Chads videos are review for Chem and Org Chem and walk you through most of the topics and some techniques you will need for the mcat and dat chem and org chem sections (from what i have heard)
Alans notes: where actually written by someone else he gives credit in one of the threads but i can not remember who is the original creator, anyways it is a compilation of multiple books, tests, study guides, and class material covered on the mcat/dat.
Please pm me your email address if you would like (alan's notes)
FYI I watched Chad's videos for both O chem and G chem. His G chem videos are great but I really feel like the O chem ones weren't thorough enough at all. Half the reactions in my Kaplan BB he doesn't even touch on.
If you'd like I can send you the study guides which are circulating around SDN. I dont know if they have changed much since I made them two summers ago, but if you want the original gangster version of them, send me a PM. Or if you just want some advice on how to utilize them best, Id be happy to offer you that much.
Alan, Srb, and others have done a great job of distributing them (thanks). I used to get hundreds of PMs which I could no longer respond to after dental school started. Luckily, these fellow SDNers have made them easy to download. Check this thread out: http://forums.studentdoctor.net/showthread.php?t=674397&highlight=Greenwave+notes
