Query: Horrible Book!

I would've given this book a -1 if I could. One of the most poorly written books ever! The most useful part of this book was the "Content Review Section", where the book goes over all the major topics. But even then the author only skimmed over the topics -- not much content review!The practice exam, like the others have said, is absolutely horrible. Tons of mistakes; it had wrong solutions marked, or more than one correct choice. In short, do NOT buy this book!
