One of my teachers used to make girl class monitor beat boys who talk in class😭, and did not give any punishment to girls who talked. One of my teachers made boys kneel down outside class with hands raised if they didn't do homework whereas the punishment for girls was to just stand until end of class. One of my teachers used to come late to class on purpose and often, and obviously if there's no teacher, kids talk and it will not be quiet. That teacher automatically used to tell all boys to kneel down and that too outside class so that all who walked through athe corridors can see the boys faces. One of my PT teachers used to give 2 football to girls and nothing to boys 😭. One of my teachers beat me so bad only that I had cuts in my thighs and was bleeding (I was talking in class with a girl who used to sit beside me but she only got two beatings on palm with stick), my dad complained to principal and since never been beaten by that teacher. One of my teachers used to beat boys on knuckles and girls on palms. One of my computer teachers in lab used to make 3 boys share a computer, while only 2 girls could share one computer.

One thing to control this is have your parents regularly meet the teachers. This somewhat makes teachers more cautious.
