Memory tips for me seem to be a bit rubbishy. Just try to study as efficiently as possible - don't get distracted, set yourself achievable goals in what you want to get done in the next hour and slap yourself in the face if you don't get it done.
This thread from just before is somewhat relevant:
Exam advice?I don't know what subjects you're doing, but for science/maths - trial exams seem to be the best way of studying. You'd be wanting to make sure you're doing them properly - timed conditions, check your working afterwards, look up and learn from your mistakes (i.e. don't go straight onto the next exam).
You may or may not find writing notes useful, but it's probably better to actually do questions for maths and physics.
This post by Shinny is pretty good (there's lots of good posts on here, not worth wasting the time to go out and find them though):
