if some one asks me how to learn biochemistry, i will recommend him dr sam turco notes/lectures. those who are interested in USMLE should listen his lectures. believe me this will help you alot, you will start loving biochemistry.
if we see past papers we come to a conclusion that biochemistry covers a major area.if you have a grip on biochemistry USMLE will be nothing for you.
