Online Registration Info
Overview
BrUMO 2026 Online will take place on March 7, 2026. There is no registration fee for this tournament, and it will happen over Zoom, so students from all around the world are encouraged to register!
To participate, teams must meet the following requirements:
Students must be in grade 12 or below at the time of participation (March 2026).
Teams must consist of 4-6 students. Applications for teams of 3 or fewer students will not be accepted.
Each team must register under one division, either Division A or B (i.e. all participants on one team will compete in the same division).
All members of the team must not be signed up to participate in the in-person BrUMO 2026 event.
Please note that, unlike our in-person competition, we do not require students on one team to come from the same school/organization!
Students who are not able to form an eligible team are also able to apply to compete as an individual, and BrUMO Organizers will randomly assign individual competitors to teams.
We will be accepting applications on a rolling basis. Once we reach capacity, we will close the registration form, even if it is before our deadline of February 15. Your application will be reviewed only if all waivers are filled out correctly, and acceptances will be sent to the coach’s email.
Divisions
All participants will be asked to choose a division when filling out the application form. As noted above, teams must register under one division. Below, we provide some guidance on how to select a division:
Division A is designed for students who have previous competition math experience, having participated in contests such as AMC 10/12, AIME, or HMMT. To gauge the difficulty of this test, please visit our Archive page and view our 2025 Individual exam.
Division B is designed to be both welcoming and challenging for those new to math contests: no concepts outside of standard high school math curriculum will be tested, with problems requiring a bit of extra critical thinking, logic, or casework. Our Division B sample test is linked here.
Students who have previous competition math experience are strongly encouraged to register for Div A. To encourage fairness, we will ask students to accurately provide their past experience on the application form, and the BrUMO team may choose to change a team’s division as we see fit.
