It’s natural to not do as well in a class with a teacher you dislike, as opposed to having a likeable teacher.
You don’t want to do their homework, or pay attention to their lectures, notes, or anything.
Talk with your school counselor and see about moving into a different class. It’s important to not change classes just because you have friends in the desired class.
Flash cards are another good thing. If he doesn’t allow formula sheets create your own and study them in advance so that your memory will carry you through the exam.
Good Luck!
Anyway, try to relax. There is more to school than teachers. You do have a life beyond school, right?
