I'm in Year 12 but definitely applying to medicine next year should everything go to plan! I got mostly A*s at GCSE and a couple of As. As for AS, I'm doing Biology, Chem, Maths & English Literature and really enjoying all of them - so much more enjoyable than GCSE because we got the freedom of choice. I'm predicted all As for AS and also doing lots of volunteering at the moment, while attempting to get hospital placements for next half-term and experience at GPs.
Everyone says AS is hard but since I really enjoy my subjects, I sort of like it being that way as you get to do more independent learning etc.
