Cramming tips (This has probs come up before)

[ledders07]

hey all,
im 16 (i know, not a student and ur age)and have exams in about 8 subjects in just less than two weeks. im from uk so im not sure what the equivalent exams are in US at 16.

anyways, what are ur best cramming tips?
is it better to work all night or get some sleep etc?

subjects are: history (cold war), geography, sciences, maths (around 18 yo level), and english literature (usual books)

Thanks a lot, much appreciated.
