For those of you who go through question books twice--why? I hear people say, "I'm going to go through this twice" like it's some magical formula for learning the material. And I just don't get how that helps. I can barely read most textbooks once, without having a sleep attack every few paragraphs. And for the question books, I always remember the right answer, so it doesn't help me. I just look at the question, hardly even reading it, and think, "oh yeah, that one was C." But if you change the scenario, who can say whether I'd get it right?
