I found it really helpful to break up the biochem chapter throughout my studying (ie 10-20 pages a week on top of whatever I studied that week) and then come back and review it all again. FA is definitely enough, but the chapter has a ton of info and sometimes does not read so well the first time around. By breaking it up, I was better able to integrate it with the other material which is very important. GOLJAN AUDIO really helped integrate material as well. Coming back to read it and turning back to relate it to the systems made it a breeze.
Biochem on my exam was sparse and very straightforward/predictable.
