Q: Here are the problems with using this in the classroom:1. The lines are not numbered, so students will have to number the lines as homework for every scene, or else you'll waste a lot of class time doing this.2. The paper quality is terrible for annotating: Mechanical pencil lead gets caught on the fibers, and any ink but ballpoint pens spreads out.3. Very few terms are annotated in the book, so you'll need to keep your own glossary inside the front cover because there's very little space to annotate.4. Prestwick House has an annotated copy with line numbers, plenty of space in the margins, high-quality paper, scene-by-scene glossary in the back, reader's tips for reading Shakespeare, and extra textbook-type help. Guess how much: 99 cents!

Q: This product does not work with my ibook G4. As stated by some earlier reviews by other customers, the charger toggles between charging and not charging. Occasionally, if it is left on, it will continuously charge. I thought about keeping it, but it is unreliable and there are other third party options for $10 more.This one is going back to Amazon.

A: Negative

Q: Prof. Jay is a genius. All of the techniques shown in this book works effectively. I use many of them during informal nhb matches and they saved my butt hundreds of times. If only Prof. Jay included some ground-fighting escapes and reversals, then I'll recommend this book to everyone, even to BJJ practitioners.

A:
Positive
