Scoring and learning coverage
Partial placement earns credit. Advanced questions use larger difficulty multipliers. Hints, retries, and slow timed answers can reduce bonuses.
Coverage includes problem definition, data preparation, leakage prevention, feature engineering, model development, validation, fairness, security, deployment, monitoring, incident response, retraining, lineage, and reproducibility.
