HMMT is organized jointly by Harvard and MIT students and runs twice a year: November at Harvard (November 7, 2026) and February at MIT (February 13, 2027). November targets teams newer to competition, spanning mid-AMC to upper-AIME difficulty. February is the elite event, running from mid-AIME into olympiad territory, with a team round requiring written proofs. A student may enter only one per season.
November uses teams of 4-6 with two individual tests, a Team Round, and a Guts Round. February uses teams of 6-8, splits the individual tests into Algebra, Geometry, and Combinatorics, and makes the Team Round proof-based with partial credit. Guts is HMMT’s signature: problems are handed out in batches, each earned by finishing the last, with estimation questions at the end.
The admissions mechanism deserves attention. Because space is limited, HMMT admits by uniformly random lottery — not first-come-first-served and not by strength — with only the previous February’s top 30 teams guaranteed a place on reapplication. For 2026-27, registration ran August 2 to September 20, at $80 per team or $10 per individual.
The practical issue for California families is distance: the main tournaments are in Boston only, with no satellite sites. HMMT does run an online version needing no registration or proctor, but it is unofficial — no rankings, no prizes — and is best used as practice.
