Without going deeply into pedagogy and didactic matters, I will attempt to keep this very black and white and simple. So please do not coment with 'open door' replies like: as a pilot you must be able to 'act under pressure', because this is not the issue and it has nothing to do with it.
A 'special exam' sort of program as such is not a bad thing at all, if it is utilised in a proper way by proper people.
For example: You will always have some candidates that very well 'know their stuff', but that same candidate would 'collapse' under the pressure of an exam. Every next exam this pressure would even get higher.
It is the task of an examiner to set an atmosphere in which a candidate feels at ease. Although this may be a very difficult task, it is as simple as that.
In regular exam exercises this may not always be possible and candidates may feel like 'sheep being led into the slaughterhouse' despite their perfect knowledge on the various subjects...
Again: 'Black and white' and simple...
Not necessarily to do with corruption...
That this scheme or program is 'corruption sensitive' like any other scheme principally has nothing to do with this and other ‘stories’...
Kind regards, learner...
