London - What do you do to celebrate when you find out that your daughter has scored the maximum 162 in a test for Mensa, the world's oldest high-IQ society?

In the case of British eye specialists Jayashree and Muniraju Ramu, the answer is simple - their reaction was extremely low-key.

When they found out in March this year that their daughter, Neha, 12 at the time, had blitzed the test, they didn't celebrate with a party or a series of loud, joyous phone calls to everyone in the family's contact list.

To put her achievement in context, the Mensa result ranks her ahead of Professor Stephen Hawking, Mr Bill Gates and even Albert Einstein, all of whom are estimated to have an intelligence quotient (IQ) of 160.

When Indian-born Neha did the test for Mensa, she found it "quite hard" and did not expect to gain admission to the prestigious high-IQ society, The Daily Telegraph reported.

The average score in Britain is around 100. The Mensa test is designed to test a range of abilities to determine a person's intelligence level.

Reflecting on her success, Neha told the British media: "I'm really, really happy because I found the test quite hard and I wasn't really holding out much hope that I'd be a member of Mensa.

"We might have a little party or something some time soon to celebrate. I haven't told my friends yet, but I've told some of my family and they are all very happy for me."

The teenager's mother said: "We found out she'd got in when my husband and I were both at work. Neha came home before us and opened the letter because it was addressed to her. She was shouting down the phone: 'I got in, I got in.'

"I am so proud of her. Although she's been doing well at these kinds of tests for some time now, this is just marvellous."

Both her parents are eye specialists and Neha intends to follow them into a career in medicine.

Chess and reading play a large part in the life of the teenager, who wants to study neurology and wants to earn a place at Harvard University.

Neha, who moved to Britain when she was seven from the southern Indian city of Bangalore, is modest about her success.

"Stephen Hawking, Albert Einstein, they've achieved so much," she told the BBC. "It's not right to compare me to them just because of my IQ.

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