The 'Wonder Twins' are set to enter secondary school at 9

Peter and Paula, from Waltham Forest, London, attend an ordinary state primary school but have already received provisional offers from more than 12 leading secondary schools.

Dubbed the "Wonder Twins", they hit the headlines when they set three world records by passing A-level and AS-level maths papers at the age of seven.

They became the youngest candidates ever to pass an A-level maths paper and the youngest twins to achieve this level in mathematics anywhere in the world.

A year later they took and passed the University of Cambridge's Advanced Mathematics (FAM) paper, becoming the youngest students ever to pass the rigorous examinations.

The twins, who take part in the Excellence in Education programme for inner-city children, have also co-authored a book with their primary school classmates – with proceeds going to charities and their school.

Their father, Chris Imafidon, said: "We're delighted with the progress they have made."

He said the youngsters would be fine at secondary school, despite the age difference with their peers, adding: "Because they are twins they have each other."

The twins' three sisters also took part in the Excellence in Education Programme, which works to develop children from socially disadvantaged backgrounds.

Their older sister Samantha, now 12, passed two GCSEs in mathematics and statistics at the age of six and their eldest sister, Anne-Marie, now 20, was the youngest girl ever to pass A-level computing, at 13. Their other sister, Christiana, 17, is the youngest schoolgirl ever to study at undergraduate level in any British university, entering at the age of 11.
