Good additional online French cours for B1-C2?
There are so many offers in the internet for learning French via Skype, that I do not know which one to choose (and not even whether this is the best way). I want to improve my spoken and written French. I tried already a tandem, but this was not satisfying for me. So has anyone made good experiences with such a cours and can recommend one? Or would you prefer other measures.
The aim is particularly, to speak French fluently (sublime language, not slang). Thanks for your answers :)
