By comparing five years of past papers, Jaya noticed a pattern. "Look," she said, spreading the 2019, 2020, and 2021 Senior Secondary Papers side-by-side. "Question 4 is always about modular arithmetic with a remainder of 7. And Question 8 is always a Diophantine equation disguised as a word problem about coins." They realized that the HKIMO didn't reward rote memorization. It rewarded pattern recognition. The past papers were not tests to be taken once; they were textbooks to be decoded.
