First off, I don't PR this forum. For school I can get my reading over with and not feel like I've wasted my time reading and rereading things that I hate. Fiction for school (and I never read fiction for pleasure) is a bit harder than textbooks because it involves a little rapid reading here and there. Mostly, however, I can superread and dip right before class and I'm good to go. Textbooks are simple: after each pass through the material, ask yourself, "do I get it now? What did I see in there that I don't yet understand?" If you have professors who actually teach, a couple SR/Dip passes on the chapter ought to suffice.
