After facing a series of academic setbacks, ultimately leading to taking a semester off, I finally found the impetus to actually do something lastingly about my fucked study habits. This book is 400 pages, dense with different methods to get more out of your study time.

It seems to be the book on proper study habits. It is super-super dense and reads more like a textbook. Filled with research, helps to put aside many of the questions I've had over the years about how to properly go about studying, such as
1. Should I listen to music when I study?
2. In lecture, should I make overly goddamned detailed notes, or just use the bare minimum for the idea?
3. study with friends, or alone?
4. when (day/night/morning) is the best time to study?
I fuckin' love this book. If you think it is too expensive, just check it out from your library, there has been like 9 editions, but they all basically say the same things, take what you can get. I'm working off a 4rth edition copy and I am really busting my ass on getting down some of the new techniques and concepts.
Now, I'm looking for a book that approaches how to take notes for different subjects/classes. IE - Organic chemistry book/lecture, history book/lecture, literature book/lecture, math book/lecture. Each subject and source (book/lecture) seems to have a more effective note-taking method that some people inadvertently fall into after practice. Anybody have some leads on this?
