i write out notes on the comp cos its quicker and clearer
then i highlight/underline them, which helps me concentrate on what I am reading, that is I dont just scan over the words.
then i cover a little bit and recite it, if I got it all, i go on to the next point, then recite the new and the old info together, if I have forgoten the previous i start from the beginning. It's that copy, cover, write, check method that I find works.
I take small chunks at a time so that I am not overwhelmed by the amount of content - i focus on only one page at a time and I think it's important to reward yourself if you've just learned something that was bitch-hard!
once you go over it once like that, it's remarkable how long you can remember the info (some things come back so quickly even after the half-yearlies in April).
Panicking ain't the way to go, cos you wont remeber alot. If you think you don't know enough, concentrate on learning things you completely dont know, rather than the things you sort-of know.
You'll be fiiiine, good luck!
