ACHIEVING an A* in maths at GCSE would be more than satisfactory by anyone's standards.

But one Coulsdon whiz-kid got full marks in all three maths modules – scoring an incredible 600 out of 600.

Tom Dann, a student at Woodcote High School, said he was "overwhelmed" when he opened his results.

On top of his glowing maths result, he gained three more A*s and six As at GCSE, as well as three distinctions in the OCR Nationals computing qualification.

Tom, who was 15 when he sat his exams, said: "I wasn't expecting to do that well but I'm really happy.

"When I opened the envelope I was really overwhelmed. I was unsure about my English result, but got an A in the end and am delighted."

His mum Karen said she would have been happy whatever Tom's results where, but that getting full marks was a "bonus".

She added: "Tom's a very modest young man, but he is exceptionally bright and we're all so proud of him.

"He's a natural when it comes to maths. We're all so proud of him."

Tom's incredible performance contributed to the school's eighth successive year of improved grades.

Woodcote High, in Meadow Rise, Coulsdon, boasted a record high overall performance, with 66 per cent of students achieving five or more A* to C GCSEs including English and maths.

Head teacher Mark Southworth said: "To continue to improve results year after year is a huge task for any school.

"But to have done it for eight consecutive years is tremendous, and is a reflection of a real willingness to make things better for our students."

In 2003, the year Mr Southworth joined the school, just 33 per cent of students were gaining five or more top GCSEs including English and maths.

Mr Southworth said: "When I arrived at the school nearly half of the students were leaving with insufficient qualifications to get onto a college course, and now practically all students who stick with us through to Year 11 are able to move to further education.

"The advent of our new sixth form has also been a catalyst for improvement."
