Hello everyone. I am an international student from Korea. I majored in econ and math as undergrad and I am doing masters in econ in Korea and I am going to apply next year. I've already taken several math graduate courses( eg) Graduate real analysis, algebraic topology, financial mathematics, etc) and got good enough gpa in math( 4.32/4.5 and 4.0/4.0 in 4.0 scale). Is taking more math just for fun a waste of time? I want to take functional analysis 1,2, convex optimization, harmonic analysis and some probability theory courses. I have my GRE, Toefl scores ready and and I am also doing my research. What are your thoughts?
