I'm a local student of HK, but now study at a boarding school in the UK for A level. I have chosen biology,chemistry,psychology. Why does HKU and CUHK require 4xA* while even KCL UCL and Cambridge require 2xA* and 1xA. Am I too late to choose an extra subject to get into HKU/CUHK? And how are medical schools in top UK universities differ from HK? I'm quite confused, on the one hand HK has cheaper tuition fees for me but very high requirements.
