Ontario Mathematics Olympiad

Each school can send one team to the OMO, which qualifies by placing in the top two in a regional competition.[3] Each team consists of one Grade 7 boy, one Grade 7 girl, one Grade 8 girl, and one Grade 8 boy. The competition has four stages; individual, pairs, team, and relay. The individual stage is completed by writing a test. The two pairs in the pairs stage are the Grade 7 boy and the Grade 8 girl, and the Grade 8 boy and the Grade 7 girl. Each pair has a set amount of questions to solve. The team stage is completed similarly, with a series of questions. The relay stage is when each member of the team receives a question to answer, but the solution for that question depends on the solution of a previous teammate's question. Thus, if any member of the team does their question wrong, the solutions afterwards are wrong as well.[1][4]

There are awards for the top three teams in each of the pairs, team, and relay stages of the competition. For the individual stage, the top three Grade 7 boys, Grade 7 girls, Grade 8 girls, and Grade 8 boys are awarded. There is also a grand prize for the overall winning team.[1][3]
