## Governing Mathematical Formulation & Units
- Formula: `Topic Coverage Ratio = (Reviewed Chapters / Selected Module Chapters) × 100; Timed Drill Rate = Questions Completed / Elapsed Minutes`
- Units: Study duration in minutes; practice score in raw correct/total; backup state in validated JSON.

## Reproducible Worked Example
Bilingual HSC Revision Session: Selecting Physics Paper 1 (Vector & Newtonian Mechanics) or Chemistry Paper 1 notes displays bilingual English/Bangla concept summaries, runs a 15-minute timed MCQ/structured check, logs weak subtopics into the local revision planner, and exports a portable JSON backup.
