Query: Stay away from this book

I purchased the book and found a great number of errors within. I contacted the primary author who advised me of the web site his company has set up to notify the public of errors within the Exam Cram series that he is involved with. There are so many that he offered to refund the money I spent on this book. He also advised me that the publisher is refusing to make changes in subsequent printings.I would not depend on it primarily for passing the test.
