What to review before taking Gen. Chem II?

Hey everyone. I took Gen. Chem I about a year ago, and don’t remember very much from it. I’m sure I’d be able to pick it up quickly, however. I am going to be taking a 6-week Chem. II course this Summer, and I’m wonder what topics I should review from Chem. I. I got an ‘A’ in Chem I, and wish to do the same in Chem. II, so I’d like to be prepared.

Thanks.
