Thanks a lot for your input! To be honest, I’m quite surprised by your assessment, especially given how selective those three schools are. I’d love to know which parts of my application you felt contributed the most (i.e. are my Olympiad medals the deciding factor, or do my other extracurriculars help as well?).
Out of interest, would you happen to know how my status as an international applicant (albeit one not needing aid) would affect my chances?
