although what @happy1 and @tsbna44 are suggesting is 100% possible it is also 100% more difficult from an admissions perspective. Your junior has the ideal math track, and econ is a great complement so the coursework is right where you want it. On the other hand, the business programs are valuing experience more than ever. Be certain that I do not agree with what is trending (I think kids should be kids), but I would be doing you a disservice if I did not share a differing view as I see things first-hand. At Babson, for example, I see the large majority of the admitted applicants for finance having finance and business experiences. This is no different at BU, BC, Northeastern, and other similar schools. Food service can absolutely be that experience as can club leadership but it needs deep thought and refection for it to be competitive in the undergraduate finance pool. If you message me directly, I would be glad to help you brainstorm strategies.
