# The old comet.cls.yale.edu Chinese grammar course [comet.cls.yale.edu](https://web.archive.org/web/20141113151338/http://comet.cls.yale.edu/mandarin/content/grammar.htm) A long time ago I downloaded this course which doesn't exist anymore(only on the Web Archives.) I built an audio epub from the sources, so I could learn it anywhere without internet access. The course is quite interesting. I still have to write programs to extract the sentences and the vocabulary, so I can import them into an Anki deck.
