It's all part of the process
I'm a CFI, and most of the students I see are from India. There seems to be a culture of "just pay to pass the exams". This exists not only with those who have attained their certificates, but also those who have just started their training.
They know once they go back to India, they will have to pay a certain amount of money to "clear the exams". They've already budgeted for that cost before their first solo.
That's not to say that they all do it. A few have told me that they have no intention of bribing anybody. However, it is more than a little concerning when people speak so casually about obtaining licenses illegally.
