AJMO vs WAJO: Which Junior Olympiad Paper Have You Found?

By Ace Achievers · Published 16 October 2026 · Official information checked 14 October 2026

Why do search results mix the two competitions?

The names share “Australian”, “Junior” and “Olympiad”, and a shortened heading can hide the word “Western”. During this review, searches for AJMO paper material returned WAJO archive pages and a third-party upload of an older WAJO file. The cover title and organiser resolve the ambiguity better than the search-result headline.

Do not interpret an archive of many earlier WAJO years as proof that the new AJMO had earlier editions. They are different series. A useful related problem can still teach reasoning, but its year and competition should remain attached to it.

What are the differences to check?

The WAJO description and format above are tied to the organiser’s current 2026 information, checked on 14 October 2026. They should not be carried forward as unchanged future-year details. The official AJMO page currently leaves date information unconfirmed; an old search snippet is not a reliable new registration date.

How do we identify a PDF correctly?

1. Open the cover or first page and read the full competition title.
2. Check the publisher or organiser and sitting year.
3. Read the number of questions, working time and answer instructions.
4. Return to the organiser’s resource page to confirm the download context.

The UWA archive links a WAJO 2026 questions-and-solutions file. This is a verified public resource for WAJO. It is not evidence of a complete AJMO 2026 paper. Our AJMO resource finder keeps that distinction alongside the actual AMT sample links.

Can a WAJO problem still be useful?

Yes, when the difficulty and method fit the child. Use one problem to practise a representation, systematic counting or number reasoning. Judge the student’s work on that task; do not calculate an expected AJMO award from a WAJO practice score. Different papers have different populations, structures and marking rules.

For an upper-primary learner, begin with the relevant AMT AJMO sample selection and secure foundations. A difficult regional paper can be interesting enrichment, but it does not need to become the first diagnostic exercise. For an older learner, compare a suitable sample of harder work and the ability to explain an argument.

What label should go in the practice log?

Record the exact competition, year, question reference, skill and help given. Keep “official AJMO sample”, “WAJO 2026”, “AIMO 2024”, and “our original practice example” as separate labels. This makes later review credible and prevents a correct method lesson from turning into an inaccurate claim about a particular exam.

A reliable preparation collection combines accurate sourcing with a useful learning sequence. More PDFs alone do not provide that sequence; choose the next task from the gap shown by the child’s independent work.
