I am currently a jr at my university which has a top 10 mfe program doing math/econ dual degree. Obviously I plan on applying to the program at my university, and I would like to take advantage of this situation and network as much as possible to help odds. After looking at their curriculum, there are a handful of graduate level math courses listed in their core classes that I can take as a senior. If I were to take some of these core courses, do well, and also establish strong rapport with my professors, would this be beneficial in the admission process?
Essentially what I want to know is how subjective are admissions for MFE programs? Assuming I have around a 3.4-3.5 gpa and a good quant score on the GRE, will making these connections give me a good leg up on the competition?
