I take my German at EB Zurich, and about to finish A2 after two years ( but its only once a week) :O
They have quite good choice of classes form once a week evening to intensive morning classes where you are able to complete one level in one months.
I am thinking of taking up some Skype conversations has any of you tried that?
I heard a klubschule recommend, specifically the branch near Lochergüt. A1 course had two teachers: one Swiss German, one German. The German was a great teacher, the Swiss German satisfactory. The course uses Schritte textbooks which are well-written and clear.
Again, just passing on the review that I heard. Best of luck.
Personally, I am doing Skype once a week to fill in some holes in my education. Good teacher, ex-university lecturer with reasonable rates and comfortable manner. Austrian native. Do PM me for details!
Best of luck,
Niko
One day a week will not work. Intensive courses are the best option to prepare you for interviews etc. That being said, Migros Klubschule is quite good and the price is resonable enough. But, in my opinion, ZHAW would be a better choice. It costs a bit more, but the team, class size and level of teaching was far better than that at Migros.
And true, my one hour a week is barely worth it, but my Skype teacher gives me homework and is generally available for a quick question or two. It's mainly for conversation practice, but if I was learning fundamentals, or in the situation of the OP, one hour a week wouldn't suffice.
