Students are evaluated for their knowledge. They are forced to leave the institution after repeated failure.
But such failure may be due to their teachers also, who may have insufficient knowledge level or teaching skills.
A teacher with some knowledge may be converted to an ordinary man or below to that level if do not study his/ her subject for a long time.
There may be arrangement of some written test for measuring the knowledge level of the teachers also at every three years or like that to force the teachers to remain updated in their subjects.
