Question-bank first
Practice is only useful when the content can be trusted.
- Trace it.Every published question keeps its source, license, review, and version history.
- Learn from it.Practice feedback connects the answer to an explanation, hint, shortcut, and topic.
- Measure it.XP rewards useful learning; mastery accounts for difficulty, recency, and confidence.
Local beta in progress
The trusted question-bank foundation is live.
Accounts, persistent progress, versioned content, practice feedback, XP, and leaderboards run on AptiTrove’s self-hosted database. The first approved production set is intentionally small while the larger review queue is curated.
