Yes I have... but only some of them. But thanks for reminding me. I forgot about them. I looked over Scherri's chem 20A exams and they're really concept base (which I like). However, I'm currently taking Schwartz and the first midterm was alot harder than Scherri's exams. I felt really prepared going in as I study off the Oxytoby book (which is considered an advance book). Unfortunately, I didn't fare too well on it. Considering the fact that 16 people had a zero out of 100 (and they really tried, not like blank exams were turn in), I did okay. I really want to recieve an A on the next one. It's one of those classes where you learn alot, but the grade doesn't reflect it. Any advice?
