How do আপনি get on a new teachers 'right side'?

She sounds pretty strict, but what did আপনি do to get on her bad side (because if আপনি were just being yourself, then she's the one who's got serious issues & would strongly recommend she should get feedback from some of your other teachers)? I know you're a pretty good student, so preferably just be quiet, back off & just do whatever she says; but if she seriously doesn't like you, I will have a talk to her!!
