I'm currently going to year 13 and I always was sure that I wanted to study biomedicine in uni, however, for the last few days, I realized that I want to do medicine. school starts in September and I haven't done any UCAT practice nor have I revised my year 12 material. In school, I'm an average student, I don't necessarily put in any effort into my subjects. My current AS predicted grades in bio maths and chem are all B's. Is it too late to do medicine?
