I'm focussing on work that has been set (e.g. EPQ dissertation, other essays and homework/reading) - once I've finished all of that, I basically plan to go over everything once. So, doing some essay plans and quotes/context for English literature, as well as some essay paragraphs/annotations of some chapters of harder texts; summary mind maps for every topic for history and reviewing flashcards for Classics (Classics is my best subject and the one I plan to do at uni, so a lot of the information is still in my head and I feel a lot more secure for it than other subjects.) I'm basically doing the same amount that I did between Year 10 and Year 11, which was reviewing stuff for content-dense subjects and ones I struggled with. I neglected my English Literature texts (except coursework ones) before Year 11 because it was my best subject and I still came out with a Grade 9!
