The HKDSE (formerly known as HKMO) is a public examination for senior secondary students in Hong Kong, which assesses their mathematical knowledge and skills.

Here are some resources where you can find past papers and study materials for solid geometry:

1. HKDSE Mathematics Examination Papers: You can download past papers and marking schemes from the Hong Kong Examinations and Assessment Authority (HKEAA) website.
2. HKDSE Mathematics Study Resources: The HKEAA also provides study resources, including past papers, marking schemes, and sample questions, on their website.
3. Solid Geometry Past Papers: You can find topic-based past papers and exercises on solid geometry from various online resources, such as:
   • HKMO/HKDSE Past Papers: A collection of past papers and solutions on various topics, including solid geometry.
   • Math Tricks: A website providing video lessons, examples, and exercises on various math topics, including solid geometry.
   • MITX: A website offering free online math courses and resources, including video lectures and practice exercises on solid geometry.
4. Textbooks and Workbooks: You can also refer to senior secondary math textbooks and workbooks that cover solid geometry, such as:
   • HKDSE Mathematics (Compulsory Part) textbooks and workbooks published by various publishers (e.g., Oxford, Longman, and Pearson).

Some specific topics in solid geometry that you might want to focus on for the HKDSE include:

• Properties of solids (e.g., surface area, volume, and angles)
• Types of solids (e.g., pyramids, prisms, and cones)
• Similarity and congruence of solids
• Mensuration (e.g., perimeter, area, and volume of solids)

Practicing with past papers and exercises will help you become more familiar with the types of questions and problem-solving strategies required for the HKDSE. Good luck with your studies!

Why use past papers

• Builds contest problem–solving skills and mathematical reasoning.
• Exposes you to common contest topics (algebra, number theory, combinatorics, geometry, inequalities).
• Tracks progress and timing under exam conditions.

Study plan (8 weeks, focused)

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.

Where to Go Next: Moving from Past Papers to Medals

Using hkimo+past+papers+senior+secondary is the first step. To actually win a medal (Gold, Silver, Bronze), you need to go beyond:

• Form a study group: Each member specializes in one topic (Algebra, Geometry, Number Theory). Swap past paper questions.
• Attend the HKIMO Workshop: Usually held in July. They use past papers as teaching material.
• Compare your answers to model solutions: Pay attention to presentation. A correct answer without logical steps gets zero marks in the Final Round.

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.
