Hello I have been admitted to all of these american schools and have conditional offers from both british schools based on AP’s. I am American but want to work in hedge fund management in the UK or Africa, and I am torn between these schools. I’m leaning towards cambridge overall and yale in the US. Do people have any alternate opinions? Thanks.
How can you go wrong with Cambridge or Yale? Considering your career interests, Wharton is not such a bad option either! 
LSE and Columbia are probably not as potent as your other options. If Cambridge if your first choice, go for it.
I love Columbia, but the engineering school is a bore. Get yourself to Cambridge as fast as possible!
