# Weak Topic Practice for CBSE & ICSE: A Data-Driven Drill System

Weak-topic practice for CBSE and ICSE students should be driven by graded evidence, not guesswork. Mingi stores learnability_metrics per subject and topic — updated from real AI grading with rolling averages, not inflated activity scores. Topics below 40% are flagged weak; 40–74% developing; 75%+ strong. The dashboard surfaces focusConcepts (needs_focus) first and recommended focus from the latest report card. The proven drill loop: generate a 20-mark worksheet on the weakest topic, solve interactively, read per-question feedback, then retry the same topic after 48 hours — same-day repeats overestimate retention. Escalate to 50-mark mixed papers once weak topics cross 60% mastery.

## Key facts

- learnability_metrics rows store subject, topic, score (0–100), mastery (weak/developing/strong), and attempt_count per user.
- Mastery thresholds: weak below 40%, developing 40–74%, strong at 75% or above — derived from rolling average of graded attempts.
- Scores update from batchUpdateLearnabilityFromGrade — each new attempt blends into the prior average, not attempt_count × fixed points.
- Dashboard sorts subjects with the most focusConcepts first; weak topics within a subject sort by lowest score ascending.
- Graded report cards include a recommended focus label and reason — fed into the next worksheet generation.
- Recommended retry gap for the same weak topic: 48 hours — same-evening repeats inflate short-term recall.
- Mingi supports 20, 50, 70, and 100 mark worksheets for CBSE and ICSE topic drills.
