For schools like ISB, NUS, etc. I'm sure you'll be fine as long as your GMAT is in range (+/- 20 points within their average) and your essays don't suck.
However, the top 16 US schools are going to be a huge stretch based on what you wrote. To be honest, all I see is math, math and more math. That will cause most adcoms concern about your ability to work well with people. Keep in mind that b-school isn't a math contest, and it's business really is not about quant/analytics (even in finance - that's for the junior employees; the partners and leaders in a firm are all about people - managing them, raising money from investors, etc.).
It's hard to say. It comes down to whether you can convince an adcom that you're as good with people as you are with numbers.
