I want to study medicine at Oxbridge but have relatively low GCSEs (1A* and 7As). My subjects in A levels are bio,chem and phy. Is there any way that I could still get accepted there if I get A*A*A* and I also give the SAT exams and get a good score showing that I have greatly improved academically. I am an international student. And during the time of my GCSES there was a lot of political instability in my country and a lot of security threats. I also had to take care of my grandmother at that time who was ill.
