Query: Pretty good, except for the practice questions.

Pros: Good book with a nice layout and summary sections at the end of every chapter. Good glossary.Cons: Practice questions sometimes misleading in how many answers the question is looking for. I believe that the actual computer-based testing tells you how many answers it requires, where this book inconsistently tells you this. Basically, it makes you sometimes doubt your learning because you aren't sure if there is more than one answer which may lead you to choose another answer that you feel may or may not be correct. I think this can be confusing and counterproductive to learning the material.
