Hi All, I am starting med school this August but have not been in school since end of 2011. I feel that I have forgotten a lot of chemistry and organic chemistry. I was wondering if it's recommended that I brush up on them this summer before I start med school. I have heard that biochem is important in med school but I never took it. Does med school require good knowledge of the premed prereqs courses like chem and physics? Are entering med students expected to know those subjects well? I just want to make sure I prepare myself adequately to give my self a good head start! Thanks for any input!
