Walsall, United Kingdom – Math prodigy Esther Okada is well on her way to get her PhD by the time she’s 14. The British girl, originally from Nigeria, enrolled in Open University when she was 10 years-old. She’s 13 and studying financial math.

Esther was homeschooled by her mom Efe, who said that when they enrolled her in school, she came home crying saying that she didn’t want to go back because she hated it.

Esther enjoyed math so much, she even wrote a book series, “Yummy Yummy Math”. Esther passed her Math GCSE with flying colors and her brother took the exam usually given to 12th grade students at age 6.

“I want to (finish the course) in two years,” Esther told media. “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.”
