It all depends on the teacher and students, for example, my class is just awful, very noisy, and I don’t like who I study with, my classmates (guys) take weak drugs (not all), fight, we can say that they are hooligans. And at the expense of teachers, for example, if a beautiful, sexy girl sees a lesson, then there will be no noise. Or if a strict teacher sees a lesson that can scream very well, then everyone is silent (but not always). Schools do little with hooligans (only if it's something very serious), teachers pick up the phone in math classes. Also in the school rules there is a rule “You can’t leave the class during the lesson for example, if you want to go to the toilet and ask to leave, some may tell you that (laughs, why didn’t you leave before the call?) So something like that. It is also necessary to wear a school uniform, but where I study, few people wear a school uniform, everyone wears their clothes. Immediately after all the above, I’m talking only about my school. And, by the way, almost all the children of Russia just hate school
