Query: Not worth it

I purchased this book to help me study for the Hobet. It was reccomended by the director of the X-ray tech program I am applying to. While I have yet to take the test, and do not know the exact layout, I think most would be better off buying one of those online study guides the best one I found was www.apexpreparation.com/hobet/ you get tons of reading and math questions for like 20 bucks! I found that to be much more helpful.The book does offer some good tips about math rules, etc. However be warned this book contains what I consider an unacceptable number of typos, spelling and grammar errors for a study guide. Anyone who bought this book will you tell you the same.Honeslty It's ok as start, but I think ivesting in an online guide would be much better. In other words don't rely on it solely!
