I'm really stressed out. My exams are coming up and I want to do really well in all 4 of them. My unit 1 exams are in May and my unit 2's are in June and I want to cover everything before then. I failed my mocks because I didn't really take them seriously. I am aiming to get an A in sociology, B in psychology, A in biology and B/C in chemistry. Is there enough time to have everything covered until May/June and does anybody know any really good revision tips?
