If a zero rating were possible....Embarrassing. I signed up for the exam early. I had to cancel. I was embarrassed.I depended on the fact that this book would be my key to passing the exam.There are multiple errors that are not even covered on the seven pages of corrections listed on the publisher's web site.I can't believe the publisher allowed this book to go to press with this many errors.Definitely a waste of money.
