Just started today, done one hour of Biology so far, done 1/8th of the notes for my first biology exam on the 16th. Gotta do the rest of the notes for biology, then do some Sociology, Economics and Psychology revision. Luckily I have 5 days between exams, and then 9/10 days between my second to last and last exams, so that's great.
Really not stressed at all, but that's just my nature. Been meaning to start revision for days, but I'm just not all that worried. I'm relaxed, and sure I'll get decent grades at least!
