Just wanted to throw in an update. Today, I borrowed a book from the library called The Study Skills Handbook (second edition, 2003). And so far, it looks great! Easy language, short sections, lots of tips and ideas, cool drawings.... I think it might be helpful for people who aren't in college, too. I really like how the author encourages you to jump to sections that you think will be most helpful. Also, if there's anyone with dyslexia reading this thread, it might be a book worth checking out (there's special mention regarding dyslexia).

Maybe I'll update the thread if I find it helpful, if people are interested.
