I want to change my deskmate. What should I say?

Tell the teacher first that you want to change your post, because you can't study hard in that post. If he doesn't change, you won't hand in your homework for a week. But you have to do it yourself, just don't hand it in, you have to do it. If you don't agree with your exam, you should hand in a blank sheet of paper. It doesn't matter if you get a grade. They bullied you, you responded fiercely, and you responded sarcastically. You throw the book on the floor and say, shit.
