Bro why is top set like this

No way it's normal that about half of y10s "chavs" (literal racists) are in 1 top set class, dude I just want to figure out what the hell the teacher is talking about can you stop screaming 6 7 please. No one wants to hear about you playing Fortnite so please sybau. Thankfully we were allowed to choose our seating plan so I don't sit next to any of them, half the lesson being spent having the teacher shout at them (but never actually do anything) is annoying as hell, I'm so close to just asking to be moved down a set
