SEAMO Preparation: Southeast Asian Olympiad Guide

SEAMO preparation trains one specific skill above all others: deciding what mathematics a problem needs when the problem refuses to say. That sounds abstract until you watch a capable student freeze on a question they could easily solve if someone told them which method to use.

Papers set by level

The Southeast Asian Mathematical Olympiad sets separate papers by school year, across a wide age range from primary through to senior school. A student sits the paper matching their level and is judged against their own band.

This matters more than it sounds. In competitions that group several years together, a younger student meets questions pitched at older students, and a modest result carries almost no information. Here the result is a genuine signal about where a student actually stands, which makes SEAMO a useful diagnostic as well as a competition.

Band definitions are set by the organisers and can change, so confirm the current mapping before registering rather than assuming last year's arrangement still holds.

Non-routine is the whole point

SEAMO belongs to the tradition that favours non-routine problems, and it is worth being precise about what that means.

A routine question says what to do: solve this, factorise that, find the area. A non-routine question describes a situation and stops. The student has to decide what the situation is really about, which representation will make it tractable, and only then which technique applies.

Most students have spent years on routine questions, so their instinct is to scan for numbers and start computing. On a non-routine paper that produces confident, fluent, wrong work. Good SEAMO preparation spends its early months breaking that instinct.

Building a repertoire of opening moves

The practical answer to "I do not know where to start" is not more topics. It is a small set of reliable first moves that work across many problems.

Draw it. A surprising share of problems that read as confusing become obvious as a picture, and this is the single most under-used move at this level.

Try the smallest case. If a problem asks about ten objects, do three. The pattern usually appears, and even when it does not, the small case shows you what the problem is actually asking.

Ask what stays the same. Many problems describe a process with something conserved throughout — a total, a parity, a difference. Finding it often solves the problem outright.

Name the unknown. Turning a wordy condition into one clean equation is frequently the whole battle.

Count the opposite. When counting the thing is hard, counting everything else and subtracting is often easy.

Five moves, practised until they are automatic, cover a large share of non-routine problems at this level. That is what a student should leave SEAMO preparation holding.

The topics underneath

The content range is the standard middle school competition spread, worked to real depth: number sense and divisibility, fractions and ratio, introductory algebra, geometry and area, and counting.

Counting deserves separate mention because the non-routine problems cluster there and school teaching covers it worst. Students who find it consistently hard will get more from our combinatorics course than from general practice, because the systematic methods are exactly what these problems reward.

What differs from a conventional course is that topics are practised on problems that never name the topic. A student who knows ratio only when a question says "ratio" has not learned ratio in any useful sense.

How SEAMO compares with the alternatives

Against AMC 8, SEAMO is slower and deeper. AMC rewards recognising a type quickly and executing; SEAMO rewards working out what the problem is before executing anything. A strong student usually does well at both, but the training emphasis is genuinely different.

Against SASMO, the two are close relatives in style, and students often sit both. SASMO's two-section structure makes the non-routine portion explicit, while SEAMO distributes that difficulty more evenly.

For students in India, all of this feeds the same base as the IOQM foundation route. The topics overlap almost entirely; what the international competitions add is exposure to problems written in a different voice, which is itself useful.

Why a separate paper per level matters for motivation

There is a second benefit to banded papers that is easy to miss and matters a great deal at this age.

A student who sits a paper written for students two years older will find most of it out of reach, and will reasonably conclude that competition mathematics is not for them. That conclusion is wrong and very hard to undo once formed.

With a level-appropriate paper, a student meets questions they can mostly attempt and a handful that stretch them. That is the right ratio for someone deciding whether they enjoy this. Several of our students who now work comfortably at senior level began with a banded paper that let them succeed before it let them struggle.

Working past papers the useful way

Most families work past papers by doing them and marking them. That captures perhaps a third of the available value.

The better routine is three-pass. First attempt the paper untimed. Then, without looking at solutions, revisit every problem you could not start and give each one a further ten minutes using the repertoire deliberately: draw it, small case, what is conserved. Only then read the solutions.

The second pass is where the learning concentrates, because it is the only part that practises starting from stuck. A student who goes straight from attempt to solutions never builds that, which is why they stay dependent on recognising problems.

What a year of preparation looks like

What a year of preparation looks like

Expect the first few months to feel unproductive, and say so to the student in advance.

A student new to non-routine problems will be stuck often. That is the intended experience: being stuck is the normal state when a problem does not tell you what to do, and a child who has not been told this concludes they are bad at mathematics.

What changes across a year is not that problems become recognisable. It is that the student stops needing them to be. They read an unfamiliar problem, recognise nothing, and reach for the repertoire anyway. That shift is the entire return on SEAMO preparation, and it carries into every harder competition they will ever sit.

Dates, levels, eligibility and registration are set by the organisers each year and vary by country. Confirm the current cycle with SEAMO before planning around it.
