These two-session papers develop the sustained proof writing needed for the national round. Each set has six original problems, arranged as two groups of three.
Practice format: 6 written-solution problems · Two sessions: 3 problems and 270 minutes per session.
For school year 9, by invitation through the Mathematik-Olympiade pathway. Grade 10 and higher-year papers differ and are not covered by these Grade 9 sets.
Five independently authored practice papers follow the stated structure. Difficulty is editorial, not statistically calibrated to a particular competition year. These papers are not endorsed by the organisers.
