🎯 Phase 21 — Advanced Adaptive Exam
Performance-driven exam adaptation: difficulty changes with student level, wrong answers trigger concept reinforcement, the next question is selected from performance signals, and mock tests adapt question difficulty.
Wrong Answer → Concept-Based Recovery
When a student answers incorrectly, the engine first reinforces the related concept instead of immediately increasing difficulty.
| Signal | Adaptive Action | Expected Result |
|---|---|---|
| Wrong answer | Identify the same concept family | Concept reinforcement |
| Low accuracy | Reduce difficulty | Easy question for recovery |
| Repeated errors | Keep reinforcement active | No premature difficulty increase |
| Recovered accuracy | Re-evaluate performance | Medium/Hard can resume when justified |
Demo Recovery Example
Chemistry · Organic Chemistry → wrong answer → Easy concept-reinforcement question → Functional-group reinforcement.
This prevents a wrong answer from immediately pushing the student into a harder question.
Adaptive Engine status: This Phase 21 demo is deterministic and integration-ready. It does not claim live AI adaptation until real student-performance data and/or an external provider is configured.
