Life / Egzamin prawo jazdy. Driving Test in Poland. Bribing the instructor? [17]

I am going for the EGZAMIN PRAWO JAZDY.I learn that the instructor can be difficult sometimes or always waiting for someone to make a mistake and finish the exam.

Does anyone know how to bribe the instructor on this exam?
I understand that it's against the law but it also possible most especially in this Xmas season when everybody is looking for a way to make the festive season more enjoyable.

Any idea will be appreciated.

Thx in advance.
