AMO grade levels explained: from Grade 2 to Grade 12

AMO is open to a wide range of ages — every student from Grade 2 through Grade 12 can take part, and each sits the paper designed for their own grade. That means the challenge grows naturally with the student, so AMO works equally well as a gentle first competition and as a serious benchmark before university.

Primary (Grade 2–5)

At the primary level, AMO offers an encouraging first taste of competition mathematics. Questions focus on arithmetic, number sense and early problem-solving, framed to be approachable. The aim here is curiosity and confidence: young children discover that maths can be a puzzle to enjoy, not a test to fear.

Middle (Grade 6–8)

The middle-school papers introduce more advanced reasoning — ratios, geometry, and early algebra — that stretches students who are building toward senior-level mathematics. This is often where students who enjoyed the primary rounds start to develop real problem-solving strategy.

Senior (Grade 9–12)

At the senior level, AMO presents demanding problems across algebra, geometry, trigonometry and pre-calculus topics. For experienced students, this is a genuine international benchmark — a chance to measure their mathematical reasoning against capable peers worldwide.

Choosing the right level

The general rule is simple: a student sits the paper for their current grade. Because the format is friendly and the scoring carries no penalty, there is no need to push a child up a level prematurely — doing well and enjoying the experience at the right grade builds far more momentum than struggling a grade too high.
