OΣC

Online Math Club 2.0

What we run, and how it works

Live olympiad classes, problem sets, mocks around contest season, and a Discord community of medalists and learners.

Weekly Classes

Live olympiad sessions

Live classes on most weekends, India time. Topics cycle through Combinatorics, Geometry, Number Theory, and Algebra over the year, moving from foundational ideas to harder material as the cohort progresses. Every session is recorded and uploaded to the Math Vault.

Problem Sets

A growing archive of problems

Problem sets aligned with class topics, posted on Discord during the cohort and archived into the Math Vault afterwards. Discussion happens in the Discord channels alongside the sets.

Mocks

RMO and INMO prep

As RMO and INMO get closer, we run mock exams to give people timed practice under contest conditions.

Community

The Discord is the heart of OMC

Past IMO medalists, INMO awardees, and a mix of teaching-experienced mathematicians and curious peers all hang out on the OMC Discord. It's where most of the day-to-day math conversation happens.
