the researchers for the Crown touched upon this in an interview. They basically looked into the likelihood of it all because they wanted to be fair; Edinburgh was Kate’s initial choice. She’d obtained a place, her friends were going there, she’d even chosen a flat. After William announced where he was going (St Andrew’s) and that he was taking a gap year… Kate followed suit… at the time, there was something like a 40% rise in applications for St Andrews. Ita a good Uni, but Edinburgh was better at the time for the course she chose. So it was pretty risky. And none of her friends took a gap year.
researchers basically concluded that there was no reasonable explanation for her change of direction. So they included it in The Crown.
The Crown’s head of research tells VF about the show’s depiction of Kate and Carole Middleton, who meet Prince William in the show’s final episodes.

I know the crown are trying to portray a nice, optimistic love story… but I don’t care how young they were. You don’t break up with someone you’re obsessed with and love, unless you’re wondering if there’s something better out there.
Wills got sucked into the Middleton clan and gave up trying to find an alternative because his choices were always limited. That three month break was an escape attempt.
