I didnt have any biochem question, there was however a question on one of the steps of glycolysis, and an identical question is present in the destroyer so dont worry AT ALL ON THE BIOCHEM
as for the ochem I had a question that had to with extraction of something like adding acid to base or a base to an acid that's it. If u know your basics you should be fine for the lab. I agree, kaplan covers it, if u need to cover some holes refer to wiki...
