Q: What does Raffles Mathematical Olympiad (RMO): Parent & Student Guide cover?
A: Formerly the Raffles Institution Primary Math World Contest (RIPMWC).

TL;DR
Registration quick answer (Singapore): Schools register pupils via Raffles Institution's official RMO portal; there is no individual sign-up. Always follow RI's RMO page for current instructions and dates: https://www.ri.edu.sg/rmo. RMO = RIPMWC 2.0. Started in 1996, re-branded in 2024, it tests Primary 4-6 pupils across two rounds (MCQ prelim → written final) with no-calculator rules. Round 2 invitations and awards are set by RI each year; check the annual circular for exact cut-offs, fees, and timelines. Treat the Junior Category as a sandbox for IP Direct School Admission (DSA) portfolios; treat the Open Category as a rehearsal for RI, HCI or NUS High pre-selection tests.
