The Last Theorem of the Hidden Floor
Mei Lin stared at the blinking cursor on her laptop screen. The search bar read: hkimo+past+papers+senior+secondary. Her finger hovered over the enter key.
It was 11:47 PM. The Hong Kong Mathematics Olympiad was in six days. Her classmates had been drilling for months, but Mei Lin had a secret weapon: the rumored "Hidden Floor" of the school library.
According to legend, the old librarian, Mr. Kwok, had a key to Room 4B—a room that didn't appear on any map. Inside were the original HKIMO past papers from 1998 to 2005, the "golden era" when problems were written by a mysterious professor who believed geometry could predict the stock market and number theory could break codes.
Mei Lin had never believed in legends. She believed in proofs.
But tonight, desperation whispered.
She printed the search results—a chaotic mix of broken links, Reddit threads, and a single PDF titled senior_secondary_2003_final_solution.pdf. The file was corrupted. Every page was blank except for the last one.
On that last page, in a faded serif font, was a single sentence:
“The answer to Question 6 is not a number. It is a floor.”
Mei Lin’s heart thumped. Question 6. The infamous HKIMO 2003 problem that no student had ever solved. The problem so hard, the exam committee had allegedly lost the official solution in a flooded basement.
She stared at the corrupted PDF again. With shaky hands, she changed the file extension from .pdf to .txt.
The gibberish that appeared made no sense—until she noticed a pattern. Every 23rd character was a digit. She wrote them down:
4 – B
She blinked. A coordinate.
The next morning, she skipped first period. The old library was empty. Mr. Kwok sat behind the desk, reading a newspaper upside down. He didn't look up.
“Room 4B?” she whispered.
He turned a page. “Doesn’t exist.”
“The answer to Question 6,” she said, “is a floor.” hkimo+past+papers+senior+secondary
Slowly, he lowered the newspaper. His eyes were sharp, amused. He reached under the desk and pressed something. A soft click echoed from the back wall. A section of the bookshelf swung open, revealing a narrow staircase going down.
Not up. Down.
“Senior Secondary,” Mr. Kwok said, standing. “Most think it means older students. But ‘senior’ also means higher. And ‘secondary’? That’s a trick. Secondary comes after primary. Primary numbers. Prime numbers.”
He led her down into a basement that smelled of old paper and ambition. On a single metal shelf sat twenty red binders: HKIMO Past Papers, 1998–2005.
“You’re the first to find them in seventeen years,” he said. “Question 6 of 2003 is inside. But the solution isn’t written.”
Mei Lin opened the binder. The problem was short. Elegant. Brutal.
“Prove that for any positive integer n, there exists a unique floor (greatest integer function) such that the sum of the first n primes plus that floor equals a perfect square.”
She read it three times. Then she laughed—not because it was funny, but because it was beautiful.
She didn’t need the solution. The search for it had already taught her the real lesson: the hardest problems don’t give you answers. They give you better questions.
Mei Lin closed the binder, thanked Mr. Kwok, and walked back upstairs into the sunlight.
Six days later, at the HKIMO, she solved every problem except one.
Question 6.
She left it blank.
But in the margin, she wrote: “The floor is 4B. Thank you.”
The examiners never understood. But somewhere in a hidden basement, an old librarian smiled.
The Hong Kong International Mathematical Olympiad (HKIMO) is a premier global competition designed to challenge students from Kindergarten through Grade 12. For students in Grades 10–12, the Senior Secondary (SS) category represents the most advanced level of the competition, requiring a deep understanding of complex mathematical concepts and sharp logical reasoning.
Success in this high-stakes exam often depends on consistent practice with HKIMO past papers for Senior Secondary, which help students familiarize themselves with the unique problem-solving techniques required. Exam Structure and Format
The HKIMO is divided into two primary stages: the Heat Round (preliminary) and the Final Round.
Heat Round: This 90-minute paper consists of 25 open-ended questions. Each correct answer earns 4 marks, totaling 100 points, with no penalties for incorrect answers. Many problems have elegant shortcuts
Final Round: This 120-minute exam includes 30 open-ended questions. Each question is worth 5 points, for a total of 150 points.
Key Rule: Calculators are strictly prohibited in all rounds. The Five Core Categories
Both the Heat and Final rounds are evenly split into five distinct mathematical areas: YouTube·Olympiad Champion Education Centre HKIMO Final Round 2024 Warm-Up Senior Secondary Group

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:
Some specific topics in solid geometry that you might want to focus on for the HKDSE include:
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!
Through reviewing hundreds of student attempts on hkimo+past+papers+senior+secondary, I have identified three fatal errors:
Q: Are HKIMO Senior Secondary past papers harder than HKDSE Maths Extended Module 2? A: Yes. HKDSE M2 tests computation and calculus. HKIMO tests pure logic and non-routine problems. A student scoring 90% in M2 might get only 40% in an HKIMO past paper without specific training.
Q: Can I use IMO (International) past papers instead? A: Only as a last resort. International IMO problems are significantly harder (designed for world champions). HKIMO is a regional qualifier. Focus on HKIMO, SIMOC, or Southeast Asian MO (SEAMO) past papers.
Q: How many past papers should I complete before the Heat Round? A: At minimum: 8 full papers. Optimal: 15-20 papers (including sectioned practice).
Q: My school doesn’t offer HKIMO training. Can I self-study? A: Absolutely. Many Senior Secondary medalists are self-taught using hkimo+past+papers+senior+secondary plus YouTube channels like Blackpenredpen (for calculus-style olympiad problems) and Numberphile (for number theory intuition).
The HKIMO is intentionally time-pressured. Practicing with a stopwatch helps you learn which problems to skip initially and which to solve first. Most top scorers aim for 80–90% accuracy on the first 15 questions before tackling the final few challenging ones.
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).
Before diving into past papers, you must understand the battlefield. The HKIMO consists of two main rounds: Working through past solutions trains you to spot
For Senior Secondary (S4-S6), the syllabus includes:
Past papers from the last 5 years show a consistent trend: 40% of the marks come from Algebra, 30% from Number Theory, and 30% from Geometry/Combinatorics.
