The real problem
Other tools generate content.
None tell you if you'll pass.
Summaries, flashcards, endless quizzes — and still no answer to the only question that matters the night before an exam: am I actually ready? StudyLumina turns your work into an objective readiness score, so you stop guessing.
Based on research in cognitive science: Roediger & Karpicke (2006) showed retrieval practice improves long-term retention by 200% vs passive re-reading. StudyLumina measures what actually sticks.
The score
A readiness score you can actually understand.
ERS is computed from five real performance factors — in code, not by AI. Every point is earned.
Try it — move the inputs
Held constant here
- Answer speed — on pace (45s per question), weight 10%
- Question difficulty — tracks accuracy in this demo; weighted 1× / 2× / 3× in the app, weight 5%
This is the shipped formula, not a mock-up: the four performance factors are renormalised to sum to 1, then multiplied by a coverage confidence term. That is why perfect answers on three questions still read "Not Ready" — accuracy without coverage is not evidence.
