I found that to be the most helpful. There are TONS of practice questions in there with really good explanations for the answers. I'd go through them in chunks of 10 or 20 questions, and time myself so I'd get used to proper pacing. This has a couple benefits. First, you'll be learning as you go from the answers. Second, you'll get a really good idea of what you're struggling with. Then you can occasionally go back and focus your studies on strategies for those areas.

I think too many people try to learn all these tricks and then never apply. Mix it up. Try practice problems and learn tricks along the way.
