The bell has rung and Class has officially begun.
The new Doctor Who spin-off show centres around a group of teens at Coal Hill School trying to figure out friends, parents, school, sex and maybe even the end of the world.

Taking on a spin-off series for such a well-loved show is a pretty daunting task, but speaking to Digital Spy, creator Patrick Ness has stressed that the two shows definitely do not need to step on each other's toes.
"[The universe is] as big as time and space, that's pretty roomy!" Ness said. "It's a lot of space - I love the idea of engaging with the universe, rather than feeling any constraints.
"Doctor Who is literally bound [only] by time and space, and you can go anywhere and have any kind of monster and if you had a chance to make up new Doctor Who monsters, wouldn't you? Wouldn't you just run and run with it?"
He also noted the extremely loyal fan base, and while Class will be exploring the Doctor Who universe, it won't disrespect it.
"I know about the extremely passionate Whovian fanbase and I have zero interest in disrespecting the show," he added.
"So I come at it as a fan and as somebody who wants to engage and wants to look at it with a [fresh] pair of eyes, which is what any spin-off does - it's what any writer does on any individual episode of Who, so I didn't feel constrained - I felt free."
Vivian Oparah, who plays Tanya in the new show, also shared her desire to look after the Doctor Who franchise.
"You'd have to live in a bubble to not know that Doctor Who's a household name, so we know how important it is," she said. "It's like everyone's handed you their baby and you have to look after it.
"But the good thing about Class is, because it stands on its own two feet so strongly, the stress is alleviated, because we're creating something so new and so fresh, so it's not too much pressure... even though people love Doctor Who and respect it so much!"
The first two episodes of Class are available to watch now on BBC Three.
