Has anyone tried using the "learn while you sleep" type tapes?
im in calculus and I was curious if it would be any help as a study aid
anyone tried em?

i'm not sure if they work or not? i've never used them. it looks like if they did work, you could just record your instructor and listen to him on repeat over night instead of buying their tapes. i haven't heard their advertisements in a long while though. if you're having trouble, look into finding a tutor. btw, you wouldn't happen to know of a research proposal i can borrow do you?
