Well, I invigilated a 1st Yr university exam on Friday, and most of the papers handed in were unintelligible. There is a major problem with language teaching here, I fear. There needs to be a better balance between grammar (students have to be taught what a verb, etc. is in their first year at uni) and enjoyable communication in the language.
Though obv I see the worst cases, because the good pupils go to prépa and the ones who are not v good at English study it at university.
Where you are, Franni, there is the added problem of the imperfect grasp many people have of correct, grammatical French. And that includes quite a few professeurs d'école, sadly.
The teaching of English in primary schools is done by the class teacher, who has no training or support, Or by "vacataires", who IME are often people with an English degree but who failed the exams to become a teacher.
And just to top off the gloom, the new reforms are definitely NOT going to improve things, au contraire. In spite of the stated aim to ensure every pupil leaving Terminale is bilingual (dixit Sarkozy the specialist).
