I'm inclined to agree with the above poster. My highest section was Ochem and although I did use the Destroyer and the roadmaps, I wouldn't focus all your energy into them because the ochem section for my DAT didn't really go into the kind of detail the destroyer does. Mainly Sn1,Sn2,E1,E2, Diels Alder...that's like the extent that I had. Alot more conceptual questions concerning stability, acidity, basicity, and such
