After results day, if you want to push Maths from Level 3 to 4 or 5 next year, where should the summer go? We ran the numbers on 2012–2024 question frequency and official HKEAA correct rates — the grade gap lives in a handful of high-frequency, low-correct-rate topics.


We tagged every one of the 831 HKDSE Mathematics (Compulsory Part) past-paper questions from 2012–2024 by topic, computed 13-year frequency for each syllabus unit, and aggregated the official HKEAA per-question correct rates. Every number is traceable, and the full dataset is free to download.
