I didnt revise for my GCSEs until a day before each exam and i must say i've never revised so much before my AS's in my life!!
Ive made some general notes for psychology. Thats about it.
For English, we've sitll not studies all the poems, and we still have another book to read through so we havent been able to do anything really!
And law.. dont ask

awful.
Have a look at whsmith they have a lot of revision guides. I went waterstones (because i love it there) but whsmith have more revision guides etc.
For my revision im going to start off by writing practice essays into note form on a4 paper, transferring it into mindmaps or tables on a3 paper. And then writing it onto revision cards.
And then i might add some post it notes here and there about how to structure the essay, or for law, i would write the details of the case on the post it note.
But i havent got that far yet, i hope i manage it though
And then after that, just to re-iterate the notes etc i shall write them out in continuos prose

! HOPEFULLY! i always plan to do all this and i never do
Good luck!!!!
