I was hoping that this book would lean more towards a study guide, but it does not. It is simply a summary of everything on the website that is available to take the tests. I also felt that it really wanted you to purchase their Learning System. The system is great if being bought by a company, but I know I do not have $800 lying around to buy it. The only helpful thing in it was a resource page for books that will help you study for the testing.
Don't buy this book unless you are looking only for a break down of the test, and sugguested study methods.
