Hey guys. RR Biochem is not really all that popular here on the forum, but given that it is written by Goljan, there might be a few who have actually gone through it. Two questions pertaining to the book: 1. Does not cover a few topics (lac operon, etc. comes to mind). Are those topics no longer important at all? 2. How predictive is the performance on the online questions that come with the book? Anyone wth experience? Also, what do those that have seen questions in Champe's book (Lippincott) think about the quality of questions as a learning tool? Thanks.
