Adaptive engine

Tracks accuracy across every topic separately. Fraction division failing? It surfaces more. Decimal multiplication clicking? It backs off.

💡

The mental shortcut

Every wrong answer shows the full solution plus a shortcut: "×9 is ×10 minus one." Over hundreds of sessions those shortcuts become reflex.
