Find Raffles Mathematical Olympiad (RMO) registration information on Raffles Institution’s official RMO page. Entry is through the child’s MOE primary school; individual or private registration is not allowed. Parents should approach the school Mathematics Department rather than look for a public purchase button.
The page reviewed on 18 October 2026 is labelled RMO 2026 and includes that edition’s results. Its categories are Junior for Primary 4–5 and Open for Primary 6. Check a new edition’s published rules before assuming the same categories or arrangements will continue.
Did you know? A practice paper and a user guide answer different questions. One lets your child explore the mathematics; the other explains how to use the competition system. Looking at both can prevent a technical uncertainty from being mistaken for a mathematical difficulty.

Practical checks before you act
Ask the school the right first question
RI’s FAQ confirms that students cannot register independently when their school does not participate or does not select them. A useful enquiry is therefore: “Is our school participating, and who coordinates the students’ entry?” That question identifies the actual decision-maker.
Share your child’s interest without assuming that a particular selection process is universal. Ask what information the school needs and when families should expect an update. Avoid paying an outside party on the understanding that lessons automatically secure competition entry.
Do not mistake online delivery for taking it at home
For 2026, Round 1 is online at the primary schools and Round 2 is written at RI. The FAQ does not allow an outside-school attempt. Online delivery is not permission to sit the paper unsupervised at home.
Before a future edition, check the venue, device arrangements and teacher instructions together. A parent can help by keeping the practical details calm and clear: where to report, what to bring and who to ask if something goes wrong. Do not reconstruct those arrangements from an old screenshot.
Read the student guide as well as the event page
The 2026 student guide distinguishes the information website from the competition portal and says login details come from teachers. It also explains checking the student profile and asking the teacher-in-charge to correct errors. A login screen is not a public registration form.
For technical problems, the guide directs students to raise a hand and let invigilators contact support. Practise asking for help early rather than experimenting with repeated device changes during a timed session. Follow the guide and teacher instructions for that edition, not troubleshooting advice copied from an unrelated platform.
Pair a past question with its actual solution
RI provides dated past Round 1 questions and solutions on the main page. Keep the year and matching file together. A solution for a similar-looking problem can be mathematically valid yet answer a different question.
Let your child attempt one problem, explain the approach and compare it with the published solution afterwards. Notice whether the difficulty was understanding the condition, choosing a representation or checking the answer. If you want to consider further support, use the existing tutor-selection guide below rather than treating a competition result as a complete diagnosis.
What to do next
Visit RI’s RMO page, confirm the edition and ask the school Mathematics Department about participation. Use the official past materials for a relaxed first look; wait for the next published school-entry instructions before treating registration as available.
