For families new to Math League, the hardest part is rarely the maths — it is working out the shape of the season. Who competes against whom, what each round is for, and where a student in China actually starts. This is a plain-language map of that path, from the first paper to the U.S. finals.
It begins with the grade band
Math League groups students by grade band rather than by a single age cut-off. Across grades 4 through 12, a student sits the paper written for their level and is read against peers in the same band — not against the whole field. That one design choice shapes everything that follows: a strong result is always a result relative to your grade, which is why the same raw score can mean very different things in different bands.
If you are still deciding which band fits your child, that question deserves its own answer — we cover it in the guide to preparing for Math League, and the full structure lives on the competition format page.

The preliminary round
The season opens with a preliminary contest. It is a written paper, taken under standard timed conditions, and its job is simple: to give every student a fair, comparable starting point. For most families this is the round you plan around first, because it sets the rhythm for everything else.
The preliminary rewards accuracy and steady pacing more than flashes of brilliance. A student who answers the questions they know cleanly, and does not haemorrhage time on the one problem they cannot crack, almost always does better than the reverse.
The open-book semifinal
What surprises most newcomers is that the semifinal is open-book. That is not a typo, and it is not a soft option. An open-book round changes what is being tested: not whether you can recall a formula, but whether you can use the right idea under pressure, with your notes in front of you.
An open book does not make a hard problem easy. It makes a well-prepared student faster — and an unprepared one realise how little a reference sheet helps when you do not yet know what to look for.
The practical lesson: a binder full of formulas is worth far less than a student who has actually worked through problems and knows which tool fits which shape of question. Preparation still wins; the book just removes memorisation as the bottleneck.
The path to the U.S. finals
Clearing the China-region rounds opens the route toward the U.S. finals — the stage where regional qualifiers from around the world meet. For a student in China, this is the long arc of the season: each round cleared is its own marker of how far they have come, and the finals are the destination that gives the earlier rounds their meaning.
What this means for planning
If you take one thing away, let it be this: plan backward from the preliminary, not forward from a vague sense of “getting better at maths.” Pick the right band, build a steady practice habit, and treat the open-book semifinal as a reason to understand rather than memorise. The finals look after themselves once the earlier rounds are handled with care.
