Previous Year CBSE Question Mapping (PYQ)

[ankit2101]

Summary

Allow admin to upload a 'Previous Year Questions' PDF for a chapter. The system flags which generated questions are similar to real CBSE board questions, marking them as 'High Priority.'

Why

The #1 most-requested feature in every CBSE student community is 'which questions are likely to appear in boards.' Mapping generated questions against PYQs using embedding similarity provides a 'board-relevance score' that dramatically increases student trust.

Implementation Notes

• Admin uploads PYQ PDF per chapter alongside the chapter PDF
• PYQ text extracted using the existing PDF extraction pipeline
• Compare generated questions against PYQ questions using keyword overlap or sentence similarity
• Questions with similarity >0.7 get a 🎯 'High Priority' badge in the test UI

Acceptance Criteria

• Admin can upload a PYQ PDF for any chapter
• High-priority questions are flagged with a badge during the test
• Summary shows how many 'board-relevant' questions were attempted
• PYQ similarity threshold configurable in admin settings
