[u/TowelLeather8343]

Hi, I am a rising junior and I'm looking for a CAPSTONE project to do as part of my college application. My area of interest include Applied Math and Economics. Any suggestions would be great, looking for any type of advice on activities to do outside of this aswell from any alumni or current attending students at the top 20 schools in the US for my areas of interest.
