What are some good books that fit that description? I'm not referring to books focused on just nuclear or organic chemistry or something like that. I feel that if I read from such a type of book, I'll be prepared enough for the USNCO to get to the study camp and hopefully IChO. I will start with my AP book (taking AP Chem this year; got an 800 on the SAT Chem this spring after my introductory course), and then do this next book if there is a recommendation.
Thanks.
