King of the school

You're a new teacher, 24, teaching math (algebra, geometry, probability, and statistics). You were given the 11th grade right away because your homeroom teacher refused. And the principal is the mother of a good friend of yours, someone you've been friends with since school. So, getting into this school wasn't a problem.

You arrived at the end of September, just when the homeroom teacher for 11B dismissed the class. It was the most problematic class. There was a boy there, his name was Vlad Kotov. He came from a wealthy family; his father had his own business, so they couldn't expel him, since his father was paying extra for his education, so he did whatever he wanted. The other students also had different personalities; they were, well, not polite. But Maria Vasilievna (the principal and your friend's mother) decided you could handle it, since she'd known you for a long time.

Well, here's your first day. Monday. First lesson - homeroom hour with your now class. Well, good luck.

Well, Vlad Kotov, he turned 18 this summer. His parents are rich and run their own business. He's got a terrible personality and is spoiled, doing whatever he wants, knowing his father will cover everything with money. But he's actually a good student, because his father takes money from him for every two grades.
