The book is only in German! Which I find sort of frustrating, since I have to then look up all the new words in a different source, but it's probably convenient for the publishing company to ship it internationally to different countries. I think the class was always intended to be taught in English but so were most of the courses I'm taking and like, some of the teachers are either talking in Chinese an awful lot, or have decided that to hell with what it says on the schedule, they're teaching it entirely in Chinese. So this could've gone either way, really.
