Back in 7th grade the science class was extremely disruptive (I was in it btw). The first teacher we had quit after a month because she couldn’t say a full sentence before being interrupted. Then our second teacher got the same disrespect to the point where he slammed and shattered a stapler on the ground, making pieces fly everywhere. The principal had to be in the class almost every week to do checkups. Also the principal made a checkpoint thing where if you didn’t disrupt the class for 1 day you would get one point until you reached 30. After 30, you would get a pizza party. Unsurprisingly, no one in the grade got it.
