Query: Extremely Superficial

I didn't find in this study guide, what I've expected (based on my experience with other study guides): (1)Precise explanations of the basic concepts, (2) Quizlets to test the important and hard to understand concepts, (3) Providing solid answers for the quizlets including the Why's and the Why Not's, (4)Concrete discussions of at least a few intricacies in each topic, (5)A thorough set of multiple choice questions at the end of each chapter, (6) A thorough explanation of the right and the wrong answers, (7)A Test Simulator CD, etc. The coverage of the topics and the multiple choice questions is "very sketchy."
