Iw ould consider myself to be a very fluent speaker of French,although I have only been there twice (and both times for short weekend trips). Both my French teachers at school were english; only the assistant was French. None of my Ffamily speak the language, so I read and listen to as much French, as possible and did the AEA this summer and AS and A2 all in one year last year.
I do some translating from French to English for a certain company.
It really is one of the more straightforward A-Levels, if you have a flair for grammar and idiom. Also, there are a lot of ways to improve fluency outside school. For example, listening to French radio/readingFrench books, or watchiong French films (La Haine is excellent, or Amelie etc etc)
