TWO brainy brothers both aced a GCSE in computer science despite being aged just 12 and 15.

Harvey Edwards and his younger brother Harold proved age is but a number, after gaining A and B grades respectively.

The Banbury siblings took their exams at Sibford School, where Harvey is a student.

Warriner School pupil Harold said: β€œIt was a bit scary. I wanted to do it with my brother and thought it would be good experience.”
