Arran Fernandez, who has been educated at home and lives with his parents in Surrey south of London, is used to breaking records, the Daily Mail reports. At 5, he passed a math GCSE, a test most students take at 15, and at 7 he became the youngest person to get an A in the advanced math GCSE.
"Math has been my favorite subject for as long as I can remember," he says.
Last summer, Arran passed the entrance exam for Fitzwilliam College at Cambridge. He has one more hurdle, the A-level physics exam.
If he enters Cambridge at 14, Arran would be the youngest student there since William Pitt the Younger became an undergraduate in 1773. Ten years later, Pitt became Britain's youngest prime minister.
Arran's ambitions lie elsewhere, with a prime number problem that has intrigued and frustrated mathematicians for 150 years.
"It would be nice to work for Cambridge," he said. "There are a few things I want to work on. I'd like to solve the Riemann Hypothesis."
