Negative Positive
Title: Well presented, but you need the study guide.
Review: This book, actually two sold as one, has a ton of exercises, with NO useful answers--as though a ploy to force you to buy the study guide. On retrospect: buy the study guide if you hope to actually DO any exercises as part of your learning. (Note to autors: break this into the TWO books you know it is, and add the answers to the odd-numbered questions, eh?)
