For senior secondary students in Hong Kong, the Hong Kong International Mathematical Olympiad (HKIMO) represents a significant step beyond the standard DSE curriculum. It is a competition that tests not just rote learning, but mathematical creativity, logical reasoning, and problem-solving speed. One of the most effective ways to prepare is by systematically working through HKIMO past papers.
Many centers give past papers exclusively to enrolled students. If you are desperate, a short-term "exam prep" package often includes 3-5 years of Senior Secondary papers.
The Hong Kong International Mathematical Olympiad (HKIMO) Senior Secondary division is a rigorous competition designed to challenge advanced mathematical thinking and problem-solving skills. Exam Structure & Scoring
Past papers reveal a consistent format aimed at testing speed and accuracy: Duration: Typically 90 minutes. Question Count: 25 questions divided into 5 exam areas.
Scoring: Each question is worth 4 marks, totaling 100 marks. Rules: No calculators are allowed.
No point deduction for incorrect answers (making it advantageous to guess rather than leave blanks). Answers are written on a separate Answer Sheet. Core Syllabus & Topics
Senior Secondary past papers focus on five primary areas, requiring deep knowledge beyond standard school curricula: Hkimo 2024 - Reviewer 1 (HR) | PDF - Scribd
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. hkimo+past+papers+senior+secondary
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.”
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. For senior secondary students in Hong Kong, the
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.
