Do you think I should tell my history teacher she doesn't know how to teach?
Why would you want to tell her that she's a bad teacher?
I just don't like her and I don't think she deserves to be my teacher.
It's not a good idea to tell someone they are bad at their job. If it's not just personal dislike, you could talk to someone else at the school. Otherwise, you should not be so rude.
She's such a b word.
It's not nice to call your teacher rude names, and it wouldn't be nice to tell her that she's not good at her job. I think you should should try to be more respectful to her.
