## Key experiences

### Keep the speed practical. Add one character at a time.

Listen at practical character speed from the beginning, adding symbols only as mastery grows. Immediate keyboard entry connects sound recognition to physical response.

- A live Koch session with immediate entry of heard code

### Look beyond the score to the symbols being confused.

Compare transmitted code with entered answers and see exactly which symbols were mistaken for others. The next step toward the ninety-percent target becomes specific.

- A result report comparing answers, input and symbol confusion

### Tune WPM and tone to the operating conditions ahead.

Adjust character speed, effective speed, tone frequency, session length and learning level independently, using one training system from first symbols to thirty WPM.

- Precise controls for character speed, effective speed and pitch

## Frequently asked questions

### What is the Koch method?

You keep a practical character speed from day one and expand only the symbol set, so you never learn to depend on slow code.

### How does the next level unlock?

A new character unlocks only once you hit the target accuracy. Sent and entered text are compared so confusion patterns stay visible.

### Can I revisit earlier stages?

Return to any unlocked set to strengthen weak symbols, with progress and settings resets kept separate.
