Thank you for the response bigbadwolf. As I mentioned, I definitely am considering a Master's in Applied Mathematics if it can come from a top university (US, Canada, UK). For such a degree, the only weakness of my application would be my less than average 3.21 GPA, but for a top MFE it seems both my GPA and work experience will be disadvanatges.
When you say I won't be able to hack it, could you explain why you think that would be the case? The shortcomings of my mathematics background? Or did something in my description of my candidature indicate a lack of aptitude? The former can be remedied, the latter probably not (but I don't see why the latter can be the case with my test scores, especially if I also add an exceptional GMAT score). It would be great to know for the purpose of both choosing appropriate schools and constructing my applications.
I am looking at Imperial College London and London School of Economics, but I don't have an interest in colleges such as Durham, SouthHampton, etc. In place of such second-tier UK schools, I'd rather attend second-tier US schools.
Let's see where my research takes me. Honestly, I'd really like to get a Master's in Mathematics (with a concentration in analysis, differentials, stochastics), but a MFE seems to offer a much clearer path to financial jobs (when only non-doctoral degrees are being considered). I am even considering a Master's in Finance, with emphasis on asset management or something similar...something that would lead to an investment banking job, even as it disqualifies me for hedge funds and the like. This **** is so confusing. You go one way thinking it's the right way to go, but then two years later you realize you should have done something different. Like I chose actuarial science for my undergrad, but after graduating realized I should have gone with mathematics and a minor in finance instead.
Thanks again for your help!
