BTW, I know Charles got an A-Level in French at school with a grade C (not very stellar then), so I assume he must speak at least basic French . William's A-Levels were in geography , history of art and biology with grades A, B and C respectively, which makes him one of the best students in the Royal Family in recent times (compared e.g. to his father, brother and uncles), but far from academically gifted.
Also, on the topic of consorts, Camilla left school with O-levels only. In other words, she didn't even get a qualification that would have enabled her to apply to a university. Compared to Camilla, Kate's qualifications (a bachelor's degree in art history) are "outstanding".
Fwiw, the Prince of Wales speaks faultless French. When Diana died there was a story in Paris Match describing how he'd spent nearly an hour at the Paris hospital with the French surgeons and medical personnel who had struggled to save her life. He asked them for details about his dying ex-wife's final hours and thanked them for their efforts. The French doctors were very moved by his anguish, and by his ability to express himself so well in their language.
And when he and Camilla were received at the Elysee Palace by President and Mrs. Sarkozy during a State visit a while back, there was more delight in the French media about Charles beautiful, effortless French.
I think he also speaks German.
