There are three ways to deal with this kind of teacher: 1, you are cruel, I am more cruel than you, and I have tried this method myself. After I was cruel to him, the math teacher in Grade Three treated me as a son (later I couldn't believe it was him because he was a famous cannon in our school). You can consider talking to the teacher after class, because sometimes the teacher is not too hard, and maybe she is too. When chatting with her, don't directly say that she is not good. Apologize first, then ask her the way of thinking and exploring, and express your opinion about her appropriately (which can be said to be the thoughts of many students in the class). With a good attitude, she may be able to accept your suggestion, and her attitude in class may change greatly in the future (this method is used by our class to unite the head teacher of Grade Two). You can consider taking the lead to complain anonymously to her. Choose which method should be considered according to the situation and try to reconcile it. I hope your relationship with the teacher will get better soon.
