Query: A Complete waste of money

I wish I had read the reviews for this guide before I wasted good money on it. First of all there is no format for this book. It is just one test question after another. Some of the questions are repeated again and again. There are questions concerning typesetting which are completely irrelevant. It's confusing and the glossary of terms and information in the back are good but after looking at the questions, I don't even trust the information. Don't waste your money on this guide. I only give it one star because I had to pick something in order to proceed.
