A Harrow teenager has beaten geniuses such as Stephen Hawking and Albert Einstein to be invited to join Mensa with the highest possible IQ score.

Fabiola Mann, 15, of Harrow-on-the-Hill, scored the highest mark of 162 on the IQ society’s test, two marks more than the scientific greats and Microsoft founder Bill Gates.

The Northwood College pupil decided to take the three-hour test in July after performing well in intelligence and maths tests, and puzzles, has been invited to join Mensa after achieving the score.

She said: “It was quite intimidating as it was in a very formal setting.

“There were about 30 other people taking the test and with the exception of one other candidate they were all adults in their 20s and 30s.

“However the Mensa supervisor was very kind and supportive and when I got the results I couldn’t believe it.”

Fabiola, who is a keen chess player, plans to use her talents to train as a surgeon and wants to study medicine at University of Cambridge after completing her GCSEs and A-levels.

Mum Rene said: “As parents we are very proud of Fabiola and we hope she will be able to use this gift in a meaningful way that helps others and utilises her potential.”
