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
HKIMO past papers can be found through various sources:
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.
