It's for Yahwe's reason i despise exams, there elitest and never show a persons true knowledge of a subject.
However, i tried to avoid a last minute rush of revision by making some short consise revision notes , then come exam time you have 20-30 pages to revise from rather than 200-300. Just make notes on notes, rinse and repeat til you have one or two pages of key points you cant remember easily.
