Thanks! Relevant from other comment: > I don't know whether you've ever experienced a foreign-language class taught by a non-native speaker, but I've taken Academic Writing classes in English at a top Chinese university and the quality was terrible.

Often, they'll have an excellent breadth of vocabulary, while being unfamiliar with many idiomatic expressions and cultural references that come naturally to a native speaker.
