TL;DR
IJIO is Singapore's two-hour, four-problem programming contest for Sec 1-2 (IP Y1-2) students. Run by the National Olympiad in Informatics committee at NUS School of Computing, it usually happens in mid-September. Roughly thirty top scorers skip NOI Round 0 and qualify directly for NOI Round 1. Even if your child focuses on Maths or Physics, IJIO prep sharpens algebraic thinking, vector logic and experimental-design skills that reappear in IP weighted assessments.
Registration quick answer (Singapore): Registration opens on the NOI Singapore site; schools may coordinate entries but eligible students can follow the official instructions directly. Dates and rules change each cycle - see https://noisg.comp.nus.edu.sg/ for current details.
