Abhinav Santhiramohan, from Luton, was awarded an A* after taking his GCSE exam seven years early. He even completed the paper with 45 minutes to spare.

The teenager, who is the daughter of Conservative Mid Sussex MP Nicholas Soames, gained 11 A*s at independent Brighton College.
The school's headteacher, Richard Cairns, said: "I think it is a proud moment for the city that a Brighton school can outperform much more selective schools in London and elsewhere in the South East."
"I really do believe that if you have a kind, considerate and supportive environment, children will achieve more than you might expect. Happy children are, by and large, successful children."
