Undergrad at Warwick vs. Bristol vs. Manchester

Hey guys,

I am a student at an international high school, and I have received offers from three UK universities so far. They are:

• University of Warwick (BSc Management)
• University of Bristol (BSc Accounting and Finance)
• University of Manchester (BAEcon Accounting and Finance - I don't understand the "BAEcon" classification)

I have been rejected from LSE and I am waiting to hear back from King's College London. My question is, if I want an FO position at an investment bank in London, which of the three universities above should I go to? I know Warwick is better, but I'm worried that BSc Management may not be as attractive to employers as perhaps Accounting and Finance. I am also open to investment banking positions abroad, as I plan on getting an MBA at an American B-School down the line anyways. My other question is, which of the three universities above (and their respective degrees) will seem most attractive to a B-School like Harvard/Stanford/Wharton? Finally, what are your thoughts on employment prospects for international students in the UK after Brexit?

Thank you in advance for your help!
