Your personal study assistant for the HKDSE
Every week starts from what the last one showed. Lumina reads the marks you lost, ranks the topics behind them, and sets the practice that follows, drawn from over 100,000 questions covering every HKDSE subject. Written answers are marked against every mark in the scheme, following the marking conventions the HKEAA publishes. The plan keeps pointing at your target grade, and the prediction never flatters you.
Find the gap. Close it. Repeat
Four stages in a loop. Start again wherever your latest practice set or mock shows marks being lost.
Diagnose →
Use the adaptive test to rank the topics costing you marks.

Practise →
Work a focused set aimed at that one topic, then read the model answer mark by mark.

Review →
Every mistake and every question you flagged, kept in one place. Go back to the scheme, see what you missed, take it again.

Plan
The week rebuilds itself around the gap, and anything you miss rolls forward.

A record that turns into your next move
Every answer you submit is measured in exam marks, then turned into the next thing worth doing.
Your work, measured in marks and hours.
One ledger holds every session and every question, the hours you put in and the marks they earned. You can see what the work was worth.
Your weakest topics, ranked by what they cost.
You stop guessing what to revise. A short test finds your weakest topics and puts practice one tap away. Whatever you keep missing goes into your plan on its own.
Your target grade, broken into weeks.
Name a grade and get a week-by-week route towards it, built around real HKDSE grade boundaries and your own term dates. A JUPAS calculator sits alongside it. The prediction never flatters you.
One companion, your plan in context.
Ask about your work and the answer draws on your own plan and the question bank. When the evidence is not there, it says so rather than filling the gap. Four response styles to pick from.
Every subject. Every mark made visible
Over 100,000 questions cover every HKDSE subject. Written questions pair stepped model answers with HKDSE-style marking schemes, so you see both the route and exactly where each mark is earned.
Marking follows the HKEAA's published conventions: error carried forward, unit and significant-figure penalties, state symbols, contradictions and response limits. Every award point is shown separately, so you can see each place a mark was won or lost.
Marking-scheme anatomy
Stepped model answers set out each award point and the marking rules behind it, instead of hiding the mark behind a final answer.
