If that's the only reason why people can't go to college, it's really hard to convince people with affection. Schools should consider the pressure from outside the school, including the pressure from parents, and the impact on subsequent students.
However, you should be rational yourself. Everyone has a time to vent their emotions, but you chose the wrong time. I suggest you apologize to one of your classmates. The more active you are, the better. Don't make people feel arrogant. If you sincerely apologize, the other party will definitely accept the apology for public opinion. If the other party doesn't accept it, let it be. If something happens, you should dare to bear it, and don't let others think that you have nothing to bear.
In fact, this is also an opportunity for you to show your courage to admit your mistakes and take responsibility. If the other person is still unwilling to forgive because he doesn't understand the status quo, then let him go. People are doing it, the sky is watching it, and they can't arouse public anger.
As for the teacher, don't care too much. You can explain to him that being a teacher will not be too cruel to you. Many times the teacher criticizes you, and all you need is an attitude of admitting mistakes and actions to correct mistakes, so you think too much.
Prepare for the college entrance examination, and the rest can be put aside for the time being. I wish you the first place in the college entrance examination.
