Since I'm still enrolled in this class, I am not totally familiar with all of the concepts on the AP Chem exam. However, I'm good with what I know. I don't know what those using this section have completed either, so post questions and I'll help you out.
We have yet to cover organic chem this year so I assume it's not that important (though if you need help with organic chem, it was my best topic in honors chem when I took it last year).
