Lydia Sebastian finished the test with minutes to spare

An incredible schoolgirl has outwitted geniuses Albert Einstein and Stephen Hawking to gain a perfect score in a Mensa IQ test.

Bright spark Lydia Sebastian nagged her parents for an entire year before they relented and let her take the famous test paper during her school holidays.

Her determination to take the test proved to be spot-on after the 12-year-old achieved the maximum possible score of 162 on the Cattrall III B paper.

Incredibly the youngster’s result beat both world famous physicists Albert Einstein and Stephen Hawking who both achieved 160 when they attempted it.

Lydia, of Langham, Essex said: “At first, I was really nervous but once I started, it was much easier than I expected it to be and then I relaxed.

“I gave it my best shot really.”

Lydia, who is about to go into her second year at Colchester County High School for Girls, said the paper challenged her language skills, including analogies, definitions and her sense of logic. But she finished it with minutes to spare at London’s Birkbeck College. (
