I've been reading about how people are complaining about the CD not working, or other issues. Let me tell you that I've never used the CD, because this book is so easy to read (probably a 7th grade reading level), and the material isn't even difficult (nutrition). Nutrition is everywhere, and those who have this class and book should have no problem passing. I'm in a nursing program right now, and this book and class are almost an afterthought. This book makes nutrition easier than it already is. One can read a chapter in 15 minutes and fully understand it. That's my perspective.....what about YOURS?
