Q: I find the information here very helpful. The author gives a good summary of how you should prepare for an exam. However, he lacks one thing. It is completely lacking in detail. For instance,he describes two scenarios on different exams with no particular detail or discussion. If you go back and review each exam question after reviewing this book it looks like you were doing most of them. But then when all was said and done, many parts didn't even apply to my test.

A:
Good Review
