Study for the tests. Don’t cry if you fail a test and realize that you should work hard but not dwell over a bad grade or her yelling at you in the end it kinda doesn’t matter. Appreciate that she is a good teacher. Keep in mind that she isn’t that mean she just can control a class efficiently to teach the most she can. Also just make your notes nice a pretty you probably would get a better grade on them that way and ask her how to improve them if you consistently get bad grades on them.
