: 120 minutes, 30 open-ended questions (6 per category).

This section requires a deep understanding of properties of integers. Focus heavily on modular arithmetic, prime factorization, divisibility rules, and finding the units digits of massive exponents. 4. Geometry

Ptolemy’s Theorem, Menelaus’s Theorem, Ceva’s Theorem, and the Heron's Formula variations.

Counting permutations where no element appears in its original position. Step-by-Step Strategy to Study HKIMO Past Papers : 120 minutes, 30 open-ended questions (6 per category)

Fai, who was slow but meticulous, created a spreadsheet. He logged every problem from every past paper from 2016 to 2022. He discovered a critical truth: The first three questions took 5 minutes each. The middle three took 15. The final two (the "killer geometry" and "combinatorial explosion") took 30 minutes each . "Stop treating it like a DSE exam," Fai declared. "You don't get points for attempting. You get points for precision . Skip the last two. Come back if you have time."

Expect questions on complex polynomials, sequences and series (including telescopic sums), and sophisticated inequalities (like AM-GM or Cauchy-Schwarz). 2. Combinatorics and Probability sequences and series (including telescopic sums)
