A、She worries that Esther can’t take care of herself. B、She doesn’t believe Esther’s learning ability. C、She pushes her to start

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 percent in a recent exam. And in case people think her parents have pushed her into starting university early, Esther emphatically disagrees.
    " I actually wanted to start when I was seven. But my mum was like ’ you’re too young, calm down. ’ " After three years of begging, mother Efe finally agreed to explore the idea.
    Esther’s mother noticed her daughter’s talent shortly after she began homeschooling her at the age of three. Initially, Esther’s parents had enrolled her in a private school but after a few short weeks, the pair began noticing changes in the youngster.
    Efe says: " One day we were coming back home and she burst out into tears and said ’ I don’t ever want to go back to that school—they don’t even let me talk!’ "
    Therefore. Efe started by teaching basic number skills at home, but Esther was miles ahead. By four, her natural aptitude for math had seen the eager student move on to very difficult parts.
