Hello,
I am trying to find a good conversation course in Zurich (Tandem is inefficient). I encountered this one:
http://www.heks.ch/de/schweiz/region...stadt-zuerich/
Any experience with this? It looks extremely cheap, but there are small groups (6-10 students in a class). Maybe the teachers are really bad (even though it seems like these classes are partially financed by some external source). Anyway, any information would be very appreciated.
