McGill, UVa, BU

Hello everyone, I’m an international students from Italy. I’ve been accepted into McGill, BU and UVa. The problem is that I can’t go to visit them so I don’t really know how and what to choose? My dream is to become a doctor so I would like to attend medical school in the future. For this reason I’m really keen on McGill because I would study in the faculty of science (Biological, Biomedical & Life Sciences), which probably would help me a little bit more in order to apply to the medical school. However BU and UVa are also good school that would help me a lot. So there is someone who can give some advice about which one could be the best choice in order to pursue medical studies?
