I will be honest with you (not to scare you), but I tutored GC for over four years. It was also my favorite class when I was in college. The test I had (on 8/3/10) was so distorted and random that I couldn't understand the questions. There was one question with indicators and pH's listed and I still don't understand what they were asking. I couldn't even understand the question. Another was an isotope of Cf is added to B-11, how many particles would be given off? I was so lost, maybe it was just me. And then there was a question about the electrolysis of water. It asked how many moles of each (O2 and H2) would be given off. Two of the answers were correct, and I guess I picked the "wrongest one" lol. I ended up with a 16 in this section, which sucks so badly and it will probably keep me out of school this time around. There really isn't much else you can do except hope for an easier test and like the above posters said, work through the destroyer and watch Chad's videos. That section was ridiculous to me and it was just funny how everything was set up, I think. That's my personal opinion though and I am not trying to scare you at all. Everyone else says this section is basic, so maybe it was just my test. Best of luck to you!
