Title is self explanatory, I qualified for the AIME (American Invitational Mathematics Examination) and got a 5 on it. Should saying that under achievements be enough, or should I go into more detail?
I suspect they will have heard of it; if not, it’s quite easy to Google.
Every single admissions officer at every single top college/university will know what AIME is; you do not need to explain it.
