AS most of the people here have said(except jake, who gives terrible advice) try to NOT cut the sleep. I have seen and experienced the "mental block" effect so many times. and this is mainly because of people lacking sleep, and studying too much even up until the exam.
What worked for me was, study really really early, like a week before. it's in this time that you really study like a madman, cover every lesson, then as the exam draws closer, study less, and relax more. Do refresher courses each day, but not in the RAWR IMMA STUDY mode.
Keeping your brain and body in good shape before the exam is best. makes you a lot fresher and makes you think/recall better too.
