I'm in a bit of a weird situation regarding college. Due to mental health problems and personal circumstances, I've been out of my lessons since early October (and spent most of AS out of lessons too). I spend all day at college in the study and have no input from teachers. Because of this, I also don't have people in my classes that I talk to as I wasn't really in lessons much to meet people.
I'm just wondering what people use to revise for the following and any advice they have or good notes they've found.
