I'm the opposite. I rarely take my text books home because they're so heavy and I just use the CD instead. For most subjects I use binders with dividers (pretty useless though, everything gets ordered differently by the end and the dividers always break). I shove all my papers in plastic pockets and folders are useless to me. Subjects with lots of note-taking, I have an exercise book for otherwise I just use a crapload of loose-leaf papers. If I have homework, I just pull out the papers I need and shove them in my diary.
Also, I never write my homework in my diary, only SAC and exam dates. I do, however, write my homework on my CAS calculator because I actually look at that.
