Hi, my GCSE grades are all decent (could get me into medicine) except my maths and science. I am planning on retaking them this year (year 12) and get the grades required for medicine. But also restarting year 12 as none of the subjects I am taking aligns with medicine. Would any of this affect my chances of getting accepted into med schools? Would I need a whole new set of a levels or just switch two to get accepted in to med schools?
