I did English lit. (A*) and geography (A) and I would say the best way to revise is practice essays!! For English lit. especially, find past paper questions or ask your teacher or make them up, write the essay, hand it into your teacher and they should mark it. If it's like my class, you'll be the only one handing in essays and it shouldn't be a problem (although I only did it in the lead up to the exam).
In geography, I had fortnightly one-on-ones with my teacher and I chose to bring past paper questions I had done (all essay style) to get feedback
