Confidence Calibration Engine

Why this exists. Self-confidence lies. The only way to know if you actually know a topic is to be forced to produce it under pressure. Rate yourself first (this commits you). Then prove it — 3-minute blurt, 3 case studies with stats, a 12-marker against the mark scheme. The system records the gap between what you thought you knew and what you actually produced. That gap is where A* is won or lost.
