I cannot say that... they are very fast responding and propose me alternative, I think that FR said no, but the question that no one can answer is why.
If I rely on some messages above it could be possible that the school is no longer in good situation with FR, maybe it's because of the MAX and it's not too a good signal for people who want to apply for FR, or maybe it's because of my school... nice but small at the North of Poland and not a "big name" like some others... Anyway I have to find a new solution.
