12-year-old girl achieves maximum score on Mensa IQ test | young people


A 12-year-old schoolgirl scored the highest possible score on a Mensa IQ test, a feat achieved by just 1% of those who pass the society entrance paper.

Lydia Sebastian completed the Cattell III B paper supervised by Mensa, the company for people with a high IQ, with a few minutes to spare during the session at Birkbeck College, London.

Lydia had asked her parents for an entire year to let her take the test, only to take the exam during her school vacation.

Her determination paid off, with Lydia scoring 162 – the maximum possible result on the test, which primarily measures verbal reasoning ability.

Lydia, from Langham in Essex, said: “At first I was very nervous but once I started it was a lot easier than expected and then I relaxed.

“I really did my best,” said Lydia, who is entering her sophomore year at Colchester County Girls’ High School.

She said the article challenged her language skills, including analogies and definitions, and her sense of logic.

Her father, Arun Sebastian, a radiologist at Colchester General Hospital, said her daughter “had looked at the websites for IQ tests herself and got interested in them and told my wife about them, so she said, ‘Why don’t you go ahead with them?

“She had been talking about it for over a year. When I heard that she had the maximum score possible, I was overwhelmed, and so was my wife.

The schoolgirl has read the seven Harry Potter books in the series three times. Lydia, an only child, is gifted in other areas and has been playing the violin since the age of four. She started talking when she was only six months old, her parents said.

“At the time, I was a trainee doctor and my wife was studying chemistry and I was away on weekends. She used to say a few words to me on the phone, ”her father said.

Although rare, with only 1% of people who take the Mensa test scoring the highest, Lydia joins Nicole Barr, 12 from Harlow, Essex, as good as Aahil Jouher, 10 years old from Blackburn, getting perfect marks this year.

Dr Amanda Potter, a psychologist at the British Psychological Society, said: “While it is important for any individual to have sufficient cognitive ability or IQ, emotional intelligence and social intelligence are also essential.

She added that all three types of intelligence are important for an individual’s success. IQ tests were still relevant, however, as they helped organizations assess an individual’s future abilities.

“We test IQ because we want to understand to what extent they will have learning agility and be able to accept new information, deal with ambiguity and complexity and think on their feet,” he said. she declared.

The Mensa-supervised IQ test, or intelligence quotient, is divided into two sections that attempt to measure mental agility. Cattell III B has 150 questions, often testing comprehension through text passages, while the maximum score achievable is 161 for adults and 162 for those under 18.

The second article, Cattell Culture Fair III A, is largely schematic, with 50 questions and a maximum score of 183. It does not include any words – eliminating the inconvenience of having English as an additional language, or problems with language processing such as dyslexia, according to the Mensa Company.

A score of 2% in either would result in an invitation to join Mensa, and there are currently just under 1,500 members of the company under the age of 18.

The youngest member of British Mensa – founded in Oxford in 1946 – is four years old, while the oldest is 104.

Other notable people who have reportedly qualified to become members of Mensa include TV presenter Carol Vorderman, journalist Bill Buckley, Adrian Moorhouse, Olympic swimming champion, and Roger Squires, Guinness World Record crossword compiler.
