Revising? No!
By definition to revise is to look over stuff you've already done, and since you've not been taught anything yet you can't revise.
To be fair to the OP though I think it was just a badly named title? I'm sure a lot of people on ere do preliminary reading for their courses but personally it's not my thing!
I've printed my past papers for next year though, and started thinking about what I want to do for my psychology coursework, as well as buying a psychology book and drawing a pretty time table to stick on my cupboards for next year lol.
Still need to print all the specifications and buy more books, before we start A2 teaching on 11th Septemember.
My exams finished in May so I'm very out of practice! Will take me a couple of weeks to adjust/settle in I think.
ETA: I think it's different for those just left AS though, because the summer hols are spent mainly looking at uni prospectuses and starting to write your personal statement. I also had another academic assignment to complete for a uni course I'm doing so I've been pretty busy!
