What did work for me was really simple. A single 8 1/2 by 11 double sided sheet of paper could usually fit everything I needed to memorize at one given time. I'd write out a cheat sheet (a very valuable exercise in condensing and distilling while reviewing) and then reproduce it from memory before and after bed three days in a row allowing a tapered amount of cheating/peeking (with the first few being pretty much all peeking). After three days, it was pretty much good as memorized.
