The fiendishly hard final-round questions would have foxed some of the brightest brains in Britain.
Spell 'neurohypophysis'? It was no problem for Nishi Uggalle – even at 12.
With cameras and an audience glaring at her, she got it spot on… and with that the youngster was crowned the winner of Channel 4's Child Genius contest.
Nishi, who has a higher IQ than Albert Einstein and Stephen Hawking, went up against William Harwood, 11, on Saturday night in a nail-biting showdown that would rival University Challenge for difficulty. She showed lightning-fast reaction-times as the pair were quizzed on their knowledge of radioactive decay and glacier formation, as well as their maths and spelling skills.
Earlier in the week she had impressed viewers with her star performance in the arithmetic round. But it was spelling that fiendish anatomical word, which refers to part of the pituitary gland near the brain, that won her the competition.
In her acceptance speech, Nishi, from Manchester, told viewers she hoped her performance would inspire other girls to pursue traditionally male-dominated subjects such as maths.
She said: 'One of the main reasons I entered myself in the competition was to show there are a lot of stereotypes about girls not being able to do maths or physics, for example. I'd like to show that that's not true at all.' Nishi's Sri Lankan parents Neelanga Uggalle, who is vice-president for IT security at Barclays, and Shiromi Jayasinghe, her accountant mother, looked on proudly from the audience as she spoke.
While many of the show's 19 entrants appeared to have pushy parents behind them, Nishi put herself forward for the prize.
Mr Uggalle, who has nicknamed her the 'human calculator', said: 'I don't think we call ourselves pushy parents simply because I think Nishi is the pushy one.'
The 'proud geek' has an IQ of 162. Einstein and Hawking are believed to have scored 160.
