You can talk to your parents about this matter. You can’t just entertain her like that. This is unacceptable behavior of a teacher. Try to record any audio or video of her if she asks you again. Try not to indulge in these things. You shouldn’t be thinking about marks at this moment. What she is doing is wrong and you need to fight against this. You can go to the principal to file a complaint against her. Bring your parents with you too. But the main thing is that you need to gather relevant evidence against her.
