In my AP class, we have the ungodly task of reading the Enduring Visions text book. That book was unclear in places and droned on and on, much like a boring lecture- scratch that, a VERY boring lecture. Chapters were 30+ pages and our typical weekly assignment was to write a complex sentence summarizing the main points of each subheading. You can imagine how tedious that is. The first week, it was 25 subheadings, trying to sort out which info we NEED and which info is pointless.
Our teacher, however, gave us an alternative- go out and buy or barrow a copy of this book. This book, she said, followed our text book exactly, only it cut out the useless information, making reading clearer and a lot shorter. To give you an idea of how short, chapter 5 in our text book was 30 pages, 25 subheadings. The same chapter in this book was a mere 10 or 11 pages with 8 subheadings.
This book has saved me from very tedious homework assignments and lessens my homework from 2 hours a night, each night, to maybe 30 minutes a night. I recommend this book to ANYONE. It is an awesome book, and I honestly have never been so happy to see a textbook (because thats what this is) in my life! It really gave me my time back.
