I'm a first-year econ major at a top-tier university in Turkey with a 4.0 GPA and my dream is to get into a good MFE program in the States. The problem is that my econ degree isn't mathematically rigorous enough. It has okay econometrics and stats (with some R programming) courses but the math doesn't really go beyond calculus 2 (and some mathematical econ) and it has very little programming (2-3 courses). So to increase my chances, I want to either minor in mathematics or double-major in econometrics.

The minor in mathematics includes courses such as linear algebra, analytical geometry, integral calculus, differential equations, mathematical statistics & probability, and real analysis as well as some (1-2) intro CS and programming courses. The reason why I don't consider math a double major is that my school's math program is infamously hard and it has many courses that won't help me with quant finance (Like topology, number theory, discreet mathematics, and whatnot which will probably drop my GPA). I also want to develop myself in other areas and I fear the math double major may eat up most of my time.

The econometrics major includes (I excluded the courses I have on my current major) linear algebra, applied statistics, financial econometrics, mathematical statistics, time-series analysis, regression analysis, mathematical finance, data mining/analysis, optimization, capital markets and portfolio management, risk analysis & actuarial sciences as well as a few more advanced statistics and some (around 4-5) CS/programming classes mainly around R and statistics.

Personally, I enjoy stats way more than I enjoy pure mathematics and I think I will have an easier time doing the double major since the first two years of econometrics is almost identical to the econ degree. But if those math classes are a must or the econometrics program simply isn't rigorous enough I think I can handle the math minor.

Thanks for your time
