they aren’t that rare, Data10. Perhaps the top 1500 or 5000 scorers on the AMC 12? Add in the international IMO students, and you have several thousand more. Now it could be those people decide to attend elsewhere, like MIT or Caltech or Princeton, or whatever, but I would have guessed that Mudd was, or wanted to be, competitive with that crowd. Something like 30,000 kids in the US score over 750 on the math section of the SAT, so that really isn’t unusual at all
