She spends her spare time in a similar way to many other ten-year-old girls - playing with Barbie dolls and making loom bands. But the key difference between Esther Okade and other children her age is that she has been accepted to study for a university maths degree - despite not going to school.
Esther, from Walsall, West Midlands, has enrolled on an Open University course months after she passed her A-levels - and wants to study for a PhD before running her own bank.
The girl, who gained a C grade in her maths GCSE aged six, has joined the course which started this month. Her younger brother Isiah is already studying for his A-levels - also aged six.
The siblings are both home-schooled by their mother Omonefe, who has converted the living room of their semi-detached, three-bedroom house into a makeshift classroom.
