She is good, no doubt about it. Professor Fu loves non-native speakers and really encourages them and pushes them. Her teaching style is excellent: she knows how to integrate material, explore new methods, and most of all make you learn even if you don't feel like you are. The beginning might be a little painful, and it is semi-time-consuming. But in the end, it is very worth it.
If you want to learn, ask questions and she'll really make your time beneficial. Questions and participation is the key to success and also to enjoyment of the class. TAs are less reliable for Chinese classes. Try to get into a section with a good TA, because they will be with you three times a week. You can learn to pronounce Chinese, speak conversationally, and read and write certain things by the end. This is pretty good, considering most people think Chinese is an extremely foreign and strange language.
If you're a native speaker, this is not the class for you: avoid it like the plague because it will be extremely boring. And again, it's okay to mess up and be wrong. She like that, even.
