I have received both the offers from Bristol and King's College London and I also meet the conditions they made. However, I just don't know which university I should choose. They are both so great.

Here are the programs I applied:
Bristol: Physiological Science
King's: Biomedical Science

I want to be a doctor in the future, Can someone tell me what's the difference between physiological science and biomedical science? And also Which UNIVERSITY I better to choose?
