FAQ

Arithmetic Online Drill Questions

What score should I aim for?

Start with accuracy above 90%. Once your accuracy is stable, increase speed. A high score with poor accuracy is not useful practice.

Is 60 seconds or 120 seconds better?

Use 60 seconds for quick warmups and 120 seconds for classic sustained speed practice.

Does the tool save my score?

The tool saves your personal best and recent attempts locally in your browser. It does not require an account.
