Lack of machines or students who are meant to be in full time study participating in full time work as well?
If you were studying anything else, you would be expected to sit an exam on a defined date. If you failed to meet this deadline... thanks for the money... better luck next time.
If there is a genuine failure by the provider to supply machines for timely completion, then maybe you would have a case... you better have made some pretty detailed notes for your year of study though!
In any case, good luck and you may be one of the few genuine students who have a genuine gripe... however, there are so many for whom being a pilot was 'good idea' and improperly executed with the benefit of an interest free student loan!
