possibly the worst teacher ever, you can't contradict anything she says otherwise it'll start an argument that'll end with you at Mr. Hart's office.
She would be a better teacher if she had more control over the class, and less of a temper. Apart from that, she's an okay teacher. As long as you treat her with respect.
if you are on her good side, she isn't bad after all.. you have to respect her more than other teachers to be in good books with her.
