How do you feel when you'r insulted by a teacher in front of everyone? In front of your whole school? college? or whatever?

today i was insulted so much so much so much and so on... for giving a test on a small sheet while the other students were giving tests on long sheets, i thought it wouldn't be a big deal if im giving a test on a small sheet. it's just a sheet after all and it doesn't really matters. But i didn't know that i would be so much insulted by my teacher in front of the whole class then after insulting me she called me out and started insulting and yelling at me in front of the whole college I was feeling so shame when the other students were looking at me while passing by.
it was such a bad day for me today and im always having that image in my mind again and again that the teacher insulted me. All of my friends plus the other students agreed that she was overacting. it was the first time i was giving that written test and i didn't know that she was super strict. That was rude.
every student hates that teacher becaue of her arrogance. Even the other other teachers dislike her. she should've warned me, and next time i wouldn't give a test on a small sheet but she just insulted me so much that i'm just feeling so hurt.
like that's not a way of warning a student.
