That sounds a lot like the k-8 class I grew up with from 1999 to 2007. We were rowdy, constantly got in trouble, constantly interrupting class. We got in trouble so often that for our 8th grade year we lost both our New York and Washington DC field trips. Ours is the only class that either of those trips were taken away. Substitute teachers always reported back horror stories of what we did while the teacher was away. Desks and seat assignments were constantly moved around to separate the disruptive problem groups to little success.
