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.
