This is a comprehensive guide to finding, using, and understanding HKIMO (Hong Kong International Mathematical Olympiad) Past Papers for the Senior Secondary (S4-S6) level.

Since the HKIMO is a distinct competition from the standard HKDSE exams, the resources are structured differently. Here is everything you need to know. hkimo+past+papers+senior+secondary

Week 1-2: Diagnostic & Topic Isolation

• Do not time yourself for the first two papers.
• On a spreadsheet, mark which questions you failed: Algebra? Geometry? Number theory?
• Use the solutions to write down one new theorem per mistake (e.g., Wilson’s Theorem for mod problems).

1. Official HKIMO Website & Social Media

The official HKIMO organization sometimes posts sample papers or "Heat Round" solutions from the previous 1-2 years. Check their downloads section during January-March (competition season). This is a comprehensive guide to finding, using,

How to use past papers effectively

1. Set a study schedule: 2–3 problems daily or 1 full paper weekly.
2. Simulate exam conditions: time limit, no notes.
3. Attempt problems before checking solutions.
4. After solving, write full, clear solutions; compare with official ones.
5. Track weak topics and make targeted reviews (e.g., inequality techniques, geometry lemmas).
6. Revisit problems you got wrong after 1–2 weeks to reinforce learning.
7. Gradually increase difficulty and reduce reliance on hints.

Week 3-4: Timed Drills (Sectional)

• Take one paper and split it into 5 sets of 4 questions.
• Give yourself 12 minutes per set.
• Goal: Speed up your mental math for the first 10 questions (which are usually easier).

Week 6: Weakness Attack

• Gather all past papers (5+ years).
• Compile all "Number Theory" questions into one document. Drill only those for 3 days.
• Repeat for Combinatorics.
