Even if they are P2F, don't they still have to meet a certain standard, particularly if it's one of the 'big three' flight schools? If that's the case, it doesn't matter how much money you throw at it, if you haven't got the ability, you won't make the grade, so surely cream will always rise? Hopefully, theses schools don't let just anyone graduate?
I'm not being facetious, this is a genuine ask.
