Thanks for your replies.
Actually , my level of French in speaking and understanding is better than English.
I known that living in Neuchâtel I'm going to improve my French confidence a lot.(listening every day the people, Tv ,radio and some classes...)
My comment about English is because I need speaking it too for have more opportunities to get a job in my field.
Of course I want to improve my French level! But this is "english forum"
