[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!
[A]: Negative
