Greetz... 2 U. Hacker - good luck in Computer Systems Engineering, it's a nice course (i'm finishing my studies in it ).
As for exam tactics - revision is ok, but you'd focus on studying the material during the course as preparation for exam, so a week before the examination takes place you can get some rest and sleep instead of long exam preparation in this time. That was proven to be one of the best tactics, besides that way you get high self-confidence in exam and won't have to worry about anything.
Listening to music while studying also proven to be useful, but it seems that you need to listen mostly same music for the same subject you're studying and listening this music right before exam could help - that's the associative memory workin'

Luck with the exam takin'!
