(CNN)At first glance Esther Okade seems like a normal 10-year-old. She loves dressing up as Elsa from "Frozen," playing with Barbie dolls and going to the park or shopping.

But what makes the British-Nigerian youngster stand out is the fact that she's also a university undergraduate.

Esther, from Walsall, an industrial town in the UK's West Midlands region, is one of the country's youngest college freshmen.

The talented 10-year-old enrolled at the Open University, a UK-based distance learning college, in January and is already top of the class, having recently scored 100% in a recent exam.

"It's so interesting. It has the type of maths I love. It's real maths -- theories, complex numbers, all that type of stuff," she giggles. "It was super easy. My mum taught me in a nice way."

She adds: "I want to (finish the course) in two years. Then I'm going to do my PhD in financial maths when I'm 13. I want to have my own bank by the time I'm 15 because I like numbers and I like people and banking is a great way to help people."
