USA(J)MO Information

What is the USA(J)MO?

  • The USA(J)MO is the national mathematics olympiad, from which top scorers are invited to the Math Olympiad Program (MOP) where the USA IMO team is selected.
  • The top roughly 200 participants from AMC 12 and AIME qualify for the USA Mathematics Olympiad (USAMO), while the top roughly 200 participants from the AMC 10 and AIME qualify for the USA Junior Mathematics Olympiad (USAJMO).
  • The USA(J)MO is a strenuous 2-day, 9-hour, and 6-problem test of challenging and intensive proof-based problems, which is the same format of testing as the IMO. The USAMO, in particular, rivals and sometimes exceeds the difficulty of the International Mathematical Olympiad.
