You're in for a treat. Mrs. Rosenthal's class was one that I always treasured throughout my high school experience. She isn't a pushover, so don't test her, but she is one of the most genuine and kindest teachers I have ever met. I suggest you take the class seriously and work hard if you want to get an A, because she can be a strict grader. The best advice I can give is to just trust her, work hard, and enjoy this wonderful teacher! -P
