Query: Great Book!

I made the mistake of listening to my course instructor and only read the limited course material. I had purchased this book with the anticipation of not taking any course study. To make a long story short, the book by far was much better than the course itself. I wouldn't waste any time taking a course but I do recommend finding out specifics to your state requirements. I don't think I could've passed the Health exam without this book.
