I am going to be brutally honest. This is just my opinion. Based on your application, I think you are a competitive applicant, especially with a USAPhO medal and AIME. However, I am puzzled as to why you are applying for economics or cs. Your awards do not reflect any achievements in computer science or economics whatsoever. I would have expected some type of USACO medal, hackathon participation, FBLA, DECA, etc. If I were you, I would apply for physics or math, because your application will be stronger for those majors rather than going against kids who are FBLA participants with years of experience or kids who have been hacking since day one. Furthermore, I don’t see an AP CS test that was taken, which will be a red flag for admission officers.
