13-year-old Neha Ramu of London's Surbiton is one of the world's most intelligent people, with a 162 IQ level.

Comparatively, scoring above 140 on the IQ test is considered "genius" level.

BBC interviewed her on Thursday to get some insight into the little genius.

"When I found out I got such a high score it was so amazing and unexpected," Ramu said.

Ramu said she likes reading and playing chess, with ambitions to study neurology at Harvard University.

"I'm really quite passionate about the subject so I think it'll be good for me as a career," she explained.

"If I don't put in my effort and make use of my IQ then there's no point in having it."

She made headlines in March when she took the IQ test and scored 162, the highest possible score achievable. She managed to best some of the world's greatest minds, including Stephen Hawking and Albert Einstein, who have scores around 160.

"Stephen Hawking and Albert Einstein, they've achieved so much that I couldn't even dream of achieving, so it's not right to compare me to them just cause of my IQ," she added.

The 13-year-old's mother Jayashree said: "From our side she definitely doesn't have any pressure, we just make opportunities for her. She does all this without much effort. She makes sure she has enough time for TV, swimming, fun times with her friends."

Ramu admitted that she loves to learn.

"I don't think I'm ever going to stop learning. I'll always be curious and I'll always be thinking 'I wonder how that works," she said.

In addition to Ramu, 16-year-old Lauren Marbe, also from the U.K., scored an IQ of 161 in February.

"My teachers knew I was quite clever because of my grades but they had always thought I was blonde and a bit ditzy. Now they keep saying 'I didn't realize you were that clever.'" Lauren explained to The Telegraph at the time.
