Start with the school round of Germany’s Mathematik-Olympiade. Read all six problems, choose four, and prepare complete written arguments at your own pace.
Practice format: 6 written-solution problems · Take-home practice: choose any 4 of 6 problems.
For school year 9. The official shared school-round sheet for years 9–10 offers six problems; the local organiser decides which problems and working arrangements apply. Our practice uses the choose-four option.
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.
