Knowledge Tracing Demo
This interactive demonstration shows how Bayesian Knowledge Tracing works. Each time you answer a question, the system's estimate of your knowledge probability updates based on the BKT parameters.

How it works
BKT uses these parameters:
- Prior (P(L₀)): 0.30 — Initial probability you know the skill
- Learn (P(T)): 0.15 — Chance of learning after each attempt
- Guess (P(G)): 0.20 — Chance of guessing correctly
- Slip (P(S)): 0.10 — Chance of making a mistake despite knowing
