Vorsprung does indeed teach German, at a comically slow, pandering pace. The authors and/or editors and/or publishers have provided a shoddily built website jam packed with tedious exercises which vacillate between cruelly repetitive and flippantly irrelevant, and they are happy to charge $250 for the whole experience.
the illustrations provided much entertainment in college, when i obviously had much better things to do with my time than consider paying an iota of attention to learning german...Wo ist dem Fort Wayne? See what I mean?
