Meet Esther Okade, the 10-year-old maths genius who's just enrolled at college....and is already top of the class, having recently scored 100% in a recent exam....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."
