DJ Fresh got 99 per cent in his high school music exam.
The 36-year-old star insists he was terrible at all of his school subjects apart from music and English and when he scored such a high grade on the test he knew he had to pursue a music career.
He said: "I wasn't good at anything apart from English and music at school. So I realised combining them was my perfect career. I got 99 per cent in [UK exam] GCSE music, but I was awful at everything else."
Fresh - whose real name is Dan Stein - was 12 years old when he started spinning the decks and despite being a laughing stock when his mother and father forked out for his first piece of "embarrassing" equipment, he gradually gained experience by DJ-ing at his friends' parties.
He added to Now magazine: "My parents bought me a Â£50 pair of decks from a charity shop. They were old disco decks with loads of lights. So embarrassing. Everyone laughed at me, but when I got good they stopped.
"I used to annoy people by forcing them to let me play at parties. But I prefer to call it persistence."
