By diligently practicing with HKIMO past papers for senior secondary, you transform from a student who memorizes formulas into a mathematical explorer who enjoys the thrill of discovery. Good luck, and may your solutions always be elegant.
HKIMO is part of a family of Olympiads. The Singapore International Math Olympiad Challenge (SIMOC) papers are very similar. Use them as proxies if Hong Kong-only papers are scarce.
The HKIMO is a prestigious contest designed to identify and nurture mathematical talent. The Senior Secondary level is tailored for students in Forms 4 to 6 (Grades 10-12). Unlike typical school exams, the HKIMO emphasizes: hkimo+past+papers+senior+secondary
Note: Be aware of the difference between HKIMO (International) and standard HK school math contests. The Senior Secondary HKIMO is highly competitive and serves as the pathway to representing Hong Kong in the IMO (International Mathematical Olympiad).
Unlike public exams, HKIMO past papers are not centralized in a government database. You have to rely on three main sources: By diligently practicing with HKIMO past papers for
Before looking for papers, it is crucial to confirm which level you need. In HKIMO, the Senior Secondary group typically corresponds to:
| Week | Focus | Past Paper Year | |------|-------|----------------| | 1 | Number Theory & Modular Arithmetic | 2019 | | 2 | Geometry (Angles, Circles, Power of a Point) | 2020 | | 3 | Combinatorics & Probability | 2021 | | 4 | Mixed Mock Exam (timed, 90 min) | 2022 | | 5–8 | Weak topic drills + full recent papers | 2023, 2024 | Unlike public exams, HKIMO past papers are not
Week 1–2: Core techniques — algebra & number theory fundamentals, problem sets.
Week 3–4: Geometry intensive — 3–4 problems/day, learn common lemmas.
Week 5: Combinatorics and counting strategies.
Week 6: inequalities and mixed-topic practice.
Week 7: Timed full papers (one every 3–4 days).
Week 8: Review hardest mistakes, polish presentation and time management.
