Out of sight out of mind. AlwaysWondering is absolutely correct in the approach she needs to take.
Aviation training seems to be the exception to the rule of the 'customer is always right'. One of the problems being at the end of the course (particularly full-time) there will be reports written by the school & if you have in their view annoyed them it might not be particularly favourable. Yes I know it's wrong but I have seen it happen, so present polite persuasion is likely to get you further than resorting to threats & contracts.
I hope this thread serves as warning to integrated training & especially putting your house on the line.
