Btw- How do you guys study for chem. Me i do a crap load of questions but i know other people spend time reading over their notes.
Well the first thing I do is summarise each subchapter into a page (I do this electronically). Then I go ahead and do the questions for the sub chapter. Repeat all that until I finish the whole chapter basically.

Then I start polishing my notes, I refer to my A+ Chem study guide and use it to fill any gaps. Sometimes the A+ notes provide a better explanation for certain concepts as well. Then I do the end of chapter/chapter summary questions and once I'm confident, I attempt the practice question from Thushan's AN study guide!

I should grab hold of a checkpoints book for Chemistry too, seems like it might be worth it!
