WALSALL, England, March 13 (UPI) -- Ten-year-old Esther Okade of Walsall, a small town in Great Britain, still plays with dolls and dresses up like Elsa from Frozen. But now she's doing it between her online math classes through Open University.
Since her enrollment in January, Esther has been at the top of her class, scoring 100 percent on her math tests.
Her mom, Efe Okade, told CNN that she noticed her daughter's advanced math ability when she was 3.
"From the age of 7, Esther has wanted to go to university," Okade told The Telegraph.
But Okade thought she was too young. Three years later, Esther pushed her mom to enroll her at Open University, which offers online degrees.
Esther is aiming to graduate with a math degree by age 13 -- and to own her own bank by 15. She also is writing a series of math books for children called Yummy Yummy Algebra.
"I like numbers and I like people and banking is a great way to help people," Esther told CNN. "I want to be a billionaire."
Meanwhile, her 6-year-old brother, Isaiah, has been studying advanced algebra and calculus, as well as taking advanced high school math tests.
Even though Esther is not the youngest child ever enrolled in college, she is on track with her career plan.
In 1981, Ruth Lawrence passed an Oxford University entrance exam at age 10 and graduated in 1985 at 13 with a degree in math.
