Biochemistry was a difficult subject for me, but I finally got into a routine that made it quite doable. I didn't study anything out of the book--the notes were completely sufficient for me, but that is just my opinion.

2nd year students told me "old tests, old tests, old tests". So, I reviewed the old tests and made certain that I knew each question that was being asked. Well, that didn't work out for me. What I ended up doing was quite simple. I read through my notes once. Then I got together with my study group and read through the notes again, hitting my highlighted stuff. Then, we took out the old tests and tried to reason through each question on our own. Unless it was a no-brainer question, we always talked about why the incorrect answers were incorrect--I think this was important. Then, we went over our notes a third time--highlighting the stuff from the old tests that we missed.

The concepts that are tested on the biochem exams are generally the same concepts that were tested on in previous years. So, it would be a good idea to go over things that you didn't quite understand from the old exams.

good luck!
