Powerful colleges and universities are sure to produce many self-taught graduates with complete and true files 12 months or so, otherwise they will claim that they have been educated for many years or can't produce a few, or they will pass the graduation files after several years of assessment.

That shows that no matter how well the advertisement is done or how well the facade is repaired, it is all false and no matter how well it is said, it is useless. The self-study exam can be passed not by mouth, but by practical things.
