14. On 3 June 1991, William was admitted to Royal Berkshire Hospital after having been accidentally hit on the side of the forehead by a fellow student wielding a golf club. The Prince did not lose consciousness, but did suffer a depressed fracture of the skull and was operated on at the Great Ormond Street Hospital, resulting in a permanent scar. He dubbed this scar a "Harry Potter scar". He was reported to have said, "I call it (the scar) that because it glows sometimes and some people notice it-other times they don't notice it at all".
15. William was educated at independent schools, starting at Jane Mynors' nursery school and the pre-preparatory Wetherby School, both in London.Following this, he attended Ludgrove School near Wokingham, Berkshire, and was privately tutored during summers by Rory Stewart. At Ludgrove he also participated in football—along with swimming, basketball, clay pigeon shooting, and cross-country running. William sat for the entrance exam to Eton College and was admitted. There he studied geography, biology and history of art at A-Level, obtaining an A in geography, a C in biology and a B in history of art. 
16. At Eton he continued to play football, captaining his house team, and took up water polo. The decision to place William in Eton went against the family tradition of sending royal children to Gordonstoun (William's grandfather, father, two uncles, and two cousins all attended); it did, however, make the Prince follow in the Spencer family footsteps, as both Diana's father and brother had attended Eton.

Then chairman of the Press Complaints Commission, John Wakeham, said of the arrangement: "Prince William is not an institution; nor a soap star; nor a football hero. He is a boy: in the next few years, perhaps the most important and sometimes painful part of his life, he will grow up and become a man."

After completing his studies at Eton, the Prince took a gap year, during which he took part in British Army training exercises in Belize, worked within English dairy farms, visited Africa, and for ten weeks taught children in southern Chile.

News of this caused a temporary increase in the number of applications to St Andrews, mostly from young women who wanted an opportunity to meet the Prince. The extra attention did not deter him, though, and he embarked on a degree course in art history, later changing his main subject to geography, and going on to earn a Scottish Master of Arts degree with upper second class honours in geography—the best degree of any heir to the throne of Britain and the Commonwealth realms. 
20. While at university, Prince William also represented the Scottish national universities water polo team at the Celtic Nations tournament in 2004.
