2020 AIME and USA(J)MO Move Online

Posted by

Today the MAA announced on their math competitions website two online competitions coming this summer:

  • AOIME (American Online Invitational Mathematical Exam) on June 6th
  • USO(J)MO (United States Online (Junior) Mathematical Olympiad) on June 19th-20th

More details are available below. This page will be updated as more information is known.


When: The AOIME will be administered from 1:30pm-5:30pm Eastern Time / 10:30am-2:30pm Pacific Time on Saturday, June 6th.

Who: The AOIME will be open to all students who qualified for the AIME I and/or AIME II this spring. Note: Students who took the AIME I in March are eligible to also compete in the AOIME.

How: Students taking the exam will be contacted by their local competition managers with information for taking the exam.

  • Students should receive their Unique ID and their school’s CEEB Code from their competition manager. This information can be used to register for the AOIME at this link.
  • Once registered, students will have access to a practice exam to get familiar with the online testing system.
  • Students must be proctored by an adult and electronic aids (including calculators) are not permitted.
  • On testing day, the full 3 hour exam must be completed within the testing window. Thus all exams must be submitted by 5:30pm Eastern Time / 2:30pm Pacific Time on June 6th.


When: The USO(J)MO will be administered on Friday, June 19th and Saturday June 20th.

Who: Students qualify for the USO(J)MO based on their AOIME scores (and, when applicable, AIME I scores). Qualifying scores will be announced after the AOIME is held. Students with both an AIME I and AOIME score can qualify with either score. A hypothetical example can be found on the MAA website here.

How: Qualified students taking the exam will be contacted by their local competition managers with information for taking the exam.
