A teenager has once again proved he is a maths master after achieving an A-level in the subject four years early.

Daniel Mullins, of Higham, who is just 14, picked up his results last week and found out he had been awarded an A* – the highest grade.

He has been teaching himself A-level maths, with a little help from his dad Mark, and decided to apply to take the test.

He said: “Loads of children could probably do the same if they trained similarly.”

His proud dad said: “It is obviously very unusual for children to do A-levels this early but he likes doing maths. It is an amazing achievement. He is pretty chuffed with himself.”

The Year 9 pupil passed his maths GCSE when he was 12 and achieved a 9 on his paper, the top mark.

And now his brother Joseph, who is 10, has followed suit and achieved a grade 5 in his foundation GCSE.

The Cliffe Woods Primary School pupil was awarded the highest possible grade for the exam.

But he says it is not because he is a maths genius – he just likes the subject and works hard at it.

They took their exams at St George's C of E School, in Gravesend – one of the only places to admit external applicants.

Both the Mullins boys were part of a “5by5” maths club at the school, in View Road, where pupils are encouraged to get a grade 5 by Year 5.

Mark added: “It is to let children who love maths get stuck in and see how far they can go. No pushing or hot-housing, just freeing their natural ability and enthusiasm like a club.

“We really want lots of children to think they could do this too, and they could. They are not mega-minds, they are just trained and it has been such good fun for them to do it.

“Every kid should excel at something before they leave primary school, be it maths or art or sport or even picking up litter or just being first to help people on the friendship bench.”

Mark said he was looking at running the programme across other schools and hopes to inspire more young people who want to become masters at maths.
