Query: Frustratingly Incomplete

It looks like the book was rushed out the door. While there seems to be some good information in it, I was repeatedly frustrated with the end of the chapter tests asking questions that were covered nowhere in the book! Then when I did the first of the included Prep Logic tests, some of the answers were opposite of what was stated in the book. If you can't be consistent within the scope of the book it really throws it's reliably into question. Don't plan on using this as your sole resource.
