AMO

It depends on your grade. The organiser lists 15 non-routine problems for Grade 3 (Primary 3), 20 for Grade 4 (Primary 4), and 25 each for Grades 5, 6, 7 and 8. Every problem is worth 1 point, so the totals are 15, 20, 25, 25, 25 and 25 points respectively.

The organiser's AMO page states the problem counts and point values but does not publish a time limit, a passing score or a fee. Treat any figure you hear from other candidates as unverified and confirm details with your local Country or Territory Partner before you register.

The page describes every item as a non-routine problem, and the stated goals are to introduce important Mathematical concepts, teach major strategies for problem solving and strengthen Mathematical intuition. Expect questions that require several connected steps and a chosen strategy, not recall of a formula or a single arithmetic operation.

Harder in reasoning, not necessarily in content. School papers reward applying a taught method quickly; AMO-style items reward choosing a method, testing it and explaining why it works. A candidate comfortable with grade-level arithmetic can still find the paper demanding because each problem is unfamiliar by design.

The organiser's page does not state a retake policy. Because AMO is offered by grade level, most candidates simply sit the paper for their next grade in a later edition. Ask your Country or Territory Partner whether any additional sitting is available in your location.

Start with the organiser's stated goals. Build accuracy on multi-step problems first, then speed. Practise writing a full explanation for every answer, since a correct number with unclear reasoning often hides a lucky guess. Only after that add timed sets, and review every error to name the strategy you missed.

Three patterns dominate. First, reading a multi-step problem once and answering an easier question than the one asked. Second, stopping at the first answer without checking whether other cases satisfy the conditions. Third, leaving reasoning unwritten, so a small slip cannot be traced during review. Slow down on reading and check each condition before finalising.
