Divisibility, prime factorization, modular arithmetic, and remainders.
The senior secondary division in HKIMO is designed to test advanced mathematical proficiency. The competition focuses on five core areas: Puzzles and deductive reasoning problems.

Grade your paper. For every question you got wrong or failed to answer, classify the error into one of three categories:

Unlike school exams, HKIMO covers topics like Modular Arithmetic and complex Combinatorics that aren't always in the standard curriculum. Key Topics to Study (Senior Secondary Level)
Power of a point, cyclic quadrilaterals, Tangent theorems.

Notice that many HKIMO questions repeat similar, specialized techniques. Focus on learning the "trick" or "key idea" behind each problem type.
As a senior student, you are expected to handle more complexity.
Involves permutations, combinations, the Pigeonhole Principle, and probability. Why Practicing Past Papers is Essential
A past paper trains you to handle the case-splitting technique. Without practicing similar problems, you would lose 50% of the marks. | | | Final Round (Global) | |
Once you are comfortable with the topics, take a full 1.5-hour heat round paper without interruptions.
These problems focus on puzzles, sequences, and situational logic. Find the two-digit number BDcap B cap D if it is divisible by 13 and its reverse DBcap D cap B has exactly 3 factors.
These two areas often differentiate top scorers in the senior division.
