HKDSE practice desk
Official source boundary
Subject names and assessment components are checked against HKEAA frameworks; curriculum wording is bounded by HKEAA and EDB documents. AceDSE is independent and does not reproduce or claim to be official examination material.
What the free diagnostic proves
The current free bank is a short multiple-choice concept check. It can flag a topic for review, but it cannot measure writing, essays, speaking, SBA, portfolios, fieldwork, performance or practical work.
Automated release gate
Every production build rejects invalid answer indexes, missing choices, generator commentary, answer-key contradictions and common broken-question language. Only a small preview is published as static data.
Paid-content rule
Extended paid sets must be human-reviewed for subject accuracy and delivered behind server-verified entitlement. Checkout remains unavailable until automatic provisioning, entitlement and billing management are connected.
