SECOND World War codebreaker Alan Turing's Sherborne School report, encouraging him to provide "sound knowledge rather than vague ideas", is to go on public display for the first time.
The report belonging to the scientist, who is widely regarded as the father of modern computing, will go on show alongside other personal items and rarely seen coding devices.
The Cambridge exhibition Codebreakers And Groundbreakers will be made up of pieces on loan from the Turing Archive held at King's College in the city.
A report from the Dorset school showed Turing, who went on to carry out groundbreaking work in cracking the Enigma encryption used by the Nazis, to have "distinct promise" in maths.
But his teacher gently scolded his presentation style, reminding him to provide a "neat and tidy solution on paper".
His physics teacher noted that he had done "some good work, but generally sets it down badly."
The teacher added: "He must remember that Cambridge will want sound knowledge rather than vague ideas."
The exhibition runs at the Fitzwilliam Museum from Tuesday until February 4 next year.
