Teachers can't get everyone's attention because they're not paying attention, making noise or sleeping when they're teaching at the blackboard. When the teacher walks around the classroom and is on the right, there is noise on the left, etc. And again, I encounter very low motivation among students. Just today, a teacher showed us the students' grades, and I can say that I did not believe my own eyes.
