Questions parents ask

Is it really free?
Yes — this quiz needs no account and costs nothing. The full site is £6.99 a month for the whole family, up to five children, with a 14-day free trial and no card needed to start.
Does it cover GCSE computer science?
The full site covers Years 6 to 11, including GCSE-level computing in Years 10 and 11 — the CPU and architecture, searching and sorting, networks and protocols, binary and logic gates. This taster focuses on KS3, Years 7 to 9.
Do I need to know how to code?
No. The questions build understanding — algorithms, how computers store data, how networks work — using plain steps rather than one particular programming language.
How are the questions marked?
Instantly, and every answer shows an explanation so a wrong answer teaches something.
