Make indepth notes and read over them daily. After you know most of them, keep reducing your notes till they become keywords which trigger a great load of information. Also manage your time well. study hard, go out with your mates and indulge in your interests.
All my friends are bitching to me about how hard it is to study. some of them don't do anything and then end up having a cry about it when they get a crap result. its quite frustrating ! but im glad that a lot of you guys feel the same way.
