I think that its only a matter of time before FTOs start passing this on to students. I heard of one school in Spain last year that gave all students who had started courses a year previous a bill for €1,000 for fuel stating the difference in the current cost to a year previous. But this was wrote in the contracts signed stating this could happen. So there was nothing the people could do about it. So make sure you check that with any potential FTO that you are considering.
