I used the newest set of Kaplan notes and thought they were excellent. I don't think the info has changed between the older and newer versions, but the layout and questions probably have to make it more user friendly. After all, that is usually the point of newer versions- to correct errors, update, and reword things that are tricky. The Biochem book covers a fair amount of Cell and Moecular Bio in the first 100 pages. I read that book twice and listened to the lectures and felt it wasn't enough so I also ended up reading the HY CMB twice just to improve my confidence in the subject. After taking the real thing I am not sure that the HY version actually helped me with any questions that the Kaplan book didn't. I definitely do not regret reading both, as these questions are very tricky andintimidating on the real test and it doesn't hurt to be really prepared and not scared of them.
