The best revision tip i have - which ive been doing is
1) do summary cards for all of the cases - but more law detail than case facts on them cos thats wat gets you marks.
2)For each topic do summary paragraphs and read and read, then re-write and get someone to test you by simply reciting the summary's.
Poor person who is testing tho, im my case its my mum - she should get and A level in law as well as me
