## Governing Mathematical Formulation & Units
- Formula: `Local Practice Accuracy (%) = (Correct Responses / Attempted Items) × 100; Spaced Review Interval I_k = I_{k−1} × Ease_Factor (bounded to local browser study calendar)`
- Units: Practice accuracy in %; response latency in seconds/item; vocabulary review intervals in days; weekly study targets in minutes/week.

## Reproducible Worked Example
Diagnostic Set Walkthrough: Completing a 10-item mixed Verbal (Text Completion / Reading Comprehension) and Quantitative Reasoning drill records per-item timing and bilingual (English/Bangla) error rationales locally in localStorage, scheduling missed GRE vocabulary roots for 1-day, 3-day, and 7-day spaced repetition without generating an official ETS scaled (130–170) score prediction.
