Geometric Tolerancing Text/Workbook to Accompany Engineering Drawing and Design

I bought this book to do some studying on my own. I bought this book because it said it was a workbook and figured I could spend a night or two and get up to speed, but there are no answers in the back, so I am rather disapointed. The text portion is good. It is a lot nicer reading than the official ANSI 14.5 book! I recommend the text portion, but the workbook portion is about useless without the answers. I see in the preface that there is a separately available teachers guide with the answers, so buy that one instead if you aren't in a classroom environment.
