Compare the three methodsSpeed test questions
Is the score a school grade?
No. It is a short NumDojo practice score based on eight questions. It is not standardised and should not be used as a school assessment.
Do you save my answers?
The numbers you enter stay in your browser; NumDojo does not send or store them. If a signed-in adult has chosen Google Analytics, NumDojo may measure the route source, question number, correctness, broad time band, score band, correct count, registration click, and optional feedback choices. Optional feedback stores only controlled choices and the page source. A separate one-hour key derived from a hash of the request IP address limits abuse.
Do I need a payment card?
No. The speed test and the Free plan do not require a payment card.
