The royal heir, 38, says he and his wife, Kate Middleton, have been homeschooling their children themselves during the coronavirus pandemic — and it’s a job that has severely tested his fortitude.

“I’ve learned through homeschooling that my patience is a lot shorter than I thought it was, that’s probably been the biggest eye-opener for me, and that my wife has super patience,” the Duke revealed on BBC Radio 5Live’s “That Peter Crouch Podcast,” which was recorded via Zoom and also at Kensington Palace in March.

“Basically we’re a good team tag session, I come in with the children and try and get them to do something and Catherine comes in when frankly everything has gone wrong,” he explained.

The Duke and Duchess of Cambridge have been holed up in their Norfolk home Amner Hall with their children, Prince George, 7, Princess Charlotte, 5, and Prince Louis, 2, during the coronavirus pandemic.

Prince George, who is in his final year of infant school at Thomas’ Battersea, clearly has an advanced math curriculum because William is struggling to master it.

“I have to admit I’m a bit embarrassed about my maths knowledge, I can’t do Year 2 maths,” he confessed.

The future king also revealed his favorite takeout dish is chicken masala.
