Black Country brainbox Esther Okade is celebrating passing her GCSE maths exam – at the tender age of just six.

The youngster, from Wolverhampton, sailed through the exam with a C grade, a whole 10 years ahead of her peers.

Esther has already turned her attention to A-level maths, which she hopes to sit in January, and has even been invited to study the subject at Cambridge University if she passes.

Her proud father Paul Okade, aged 38, said today: “I don’t think she really realises what all the fuss is all about. We’re so very proud of her and we’re speechless by what she has done.”

Esther is home-schooled by her mother Omonefe, aged 32, a mathematician and electrical engineer.

She sat the exam in a private room at Ounsdale High School in Wombourne.

Mr and Mrs Okade, of Mandale Road, in Wednesfield, said Esther had shown a knack for numbers from an early age and knew her times tables by the age of three-and-a-half.

She soon moved on to quadratic equations and algebra, before trying out GCSE past papers, a good ten years before her peers will sit the same exam.
