A LONDON schoolgirl who became one of the youngest people ever to pass Mensa’s IQ test
with a perfect score has revealed that she was “dumbstruck” by the result.
Bianca Mudumbi, 11, was told she passed the prestigious IQ test last month.
The Pinner-based student, who is currently in year 6 at Haberdashers Aske’s Girls School,
said she thought her father was playing a trick on her when he revealed her high score.
“At first I thought my dad was pulling a prank on me,” she told Eastern Eye on Monday (25). “I was dumbstruck – I hadn’t really thought about the result.”
Bianca took the two-hour, two-part exam, which she described as “being about verbal and
non-verbal reasoning”, at Birbeck, University of London.
“I found the verbal reasoning ok, but some of it was confusing,” she revealed.
However, a few weeks later, she received a letter to confirm she had achieved 162 – a perfect score. It surpassed those of renowned scientists Stephen Hawking and Albert Einstein.
It was her father, Anil Mudumbi, who initially entered her for the exam. The 42-year-old said he noticed his daughter was exceptional at solving puzzles. She had always shown an interest in topics concerning science and maths – the pair regularly watched astronomy and physics videos on YouTube together.
“She has always enjoyed puzzles and things like that,” Mudumbi told Eastern Eye. “But I didn’t want to put any pressure on her [with the test.] I booked it but didn’t tell her what
it was about.”
Instead, he told Bianca that it was a test designed to “make her understand herself better”.
When they got the scores back from Mensa, Mudumbi admitted he didn’t quite appreciate how high Bianca’s final scores were.
“It was 162 but I assumed it was out of 200 or something,” he said. “It was only when I told my brother and he did some research and found 162 was a really good score – we discovered it was a ‘perfect score’ in Mensa terms for kids.”
After passing the test, Bianca is now eligible to apply for a membership to join the High IQ Society.
She attended her first ‘Mensa meeting’ last week at a venue in central London.
Members were able to interact with one another and play board games. Bianca said she enjoyed the experience and is keen to attend more Mensa events.
“They were quite a few young people there,” she recalled. “But I was definitely the youngest.”
Young people in Mensa are encouraged to join the Junior & Teen Special Interest Group,
which has its own newsletter, with stories, pictures and reviews by the youngest members.
Bianca, who revealed that she loves to read fantasy fiction and is an aspiring author, expressed excitement at the idea of writing for the newsletter.
“Mensa has some extra curriculum things you can do, such as clubs. I was thinking about joining one, or maybe running one when I’m older,” she added.
Mudumbi hopes the Mensa experience will help his daughter to “understand herself” and boost her confidence.
“She has concerns about global warming and she has spoken about wanting to do something to help the environment,” he said. “Bianca has a lot to offer as she grows older.”
Sadiq Khan calls Diwali on the Square a “festival of unity” celebrating London’s diversity.
Thousands gathered at Trafalgar Square for music, dance, food and family-friendly activities.
Organised by Diwali in London Committee with Chinmaya Mission UK as chair.
Deputy High Commissioner Kartik Pande calls Diwali a symbol of India-UK friendship.
MAYOR of London Sadiq Khan described this year’s Diwali on the Square at Trafalgar Square as a festival of unity that brought hundreds of people together over the weekend.
The annual free event, themed “Educate, Illuminate, Celebrate”, drew long queues stretching for miles as crowds gathered for Indian music, dance performances, devotional bhajans, and street food stalls. The family-friendly activities included sari and turban tying, yoga and meditation sessions, henna art, puppet shows, and dance workshops.
“Those of you here are proud Londoners, proudly British, proudly English, but also proudly Hindu, Sikh and Jain; you can be a proud Londoner and celebrate Diwali,” Khan said, addressing the crowd.
“Yet there are people across our country and across the globe that try and divide communities, try and turn one against the other – turn Hindus against Sikhs, or Muslims against Jews, or Christians against Buddhists, you show our city at its very, very best. You show the importance of the teachings of Diwali… how light defeats darkness, good defeats evil,” he said.
Thank you to everyone who joined us to share in the spirit of Diwali on Trafalgar Square today and celebrate the triumph of light over darkness.

The Mayor said Diwali celebrations in the “most famous square in the world” represent why London is the “greatest city in the world”.
Diwali on the Square was organised in partnership with the volunteer-led Diwali in London (DiL) committee, supported this year by Chinmaya Mission UK as chair, along with partner organisations Remitly, Lidl, and Daawat.
“It has been a privilege to serve as part of the chair team in helping to coordinate this spectacular and popular annual event in the heart of London’s iconic square, which brings together a diverse range of organisations and communities in a spirit of unity,” said Dr Milen Shah of Chinmaya Mission UK.
“This enjoyable, educational, and wonderful event will shine a light on the deeper meaning and purpose of Diwali for all who attend,” he said.
The celebration opened with around 200 dancers from different parts of India performing in the centre of Trafalgar Square, followed by musical performances and dance-dramas depicting the story of Diwali and how it is celebrated across communities.
“At its core, Diwali is a joyful celebration of the universal values of harmony, strength in diversity and hope,” said Kartik Pande, Deputy High Commissioner of India to the UK.
“This festival also epitomises the energy, creativity and contribution of the Indian diaspora and community that has enriched the very fabric of the social life of this great city. It is also a vibrant symbol of the India-UK friendship, and the recently concluded successful visit of Prime Minister Starmer (to India) adds another element of bonhomie,” he said.
Starmer was in Mumbai last week for a two-day visit during which both countries agreed to give fresh momentum to the India-UK Comprehensive Strategic Partnership and build on opportunities from the Free Trade Agreement (FTA) agreed in July.
“We are honoured to join London’s South Asian communities in marking this significant cultural tradition, one that continues to enrich the city’s diverse fabric while inspiring people worldwide,” said a spokesperson for international money transfer firm Remitly.
“As a company dedicated to fostering connection and care, we take pride in supporting this important festival and reinforcing our ongoing commitment to the communities we serve,” the spokesperson said.
“With cultural marquees and family-friendly activities throughout the square, there was something for everyone to enjoy,” added Sarita Menon from the Diwali in London Committee.
