Not trying to cram online advice rather than study..Everyone is right & everyone is also a tiny bit wrong, because its only what suits you that will work.. Personally I rewrite (I'm sitting my Masters final in 3 weeks) lectures, notes etc in my own version, not full length but so I comprehend the essence but in my own words, back this up with Google alerts so I get the latest gen on my studies, reread one section with the course notes at hand per evening (this only takes an hour and so doesn't become a huge labor) and during this alter my notes (netbok stored) so that with the past exam questions at hand, I can alter or add anything I've missed. Find somewhere you can work minus distractions..It's not the most fun activity, but repetition, reading through ,including news articles, blogs etc, (this is the purpose of Google alerts, currently I've got students in Florida posting their lectures & discussions online & professional bloggers which means I see points from them I could have missed) and practice will work. Sleep deprivation is however a constant..Zzzz...Good luck
