Usually i read for exams the day before.I never like to write exams.But if i write an exam I will star fearing of my marks.
LOL z i just listen to class and at last do night out before exams , this is my method to score 80% in all subjects.
the most effective technique I ever used was audio notes. First do the usual job of condensing your notes down to a set of core information which has to be learned. Then just read these notes fairly quickly. Record yourself and make an MP3. Play this back several times when you want to study. The big advantage here is that it doesnt even feel like study and because its low stress, the information seems to slide in easily and stay there.
