All students just get passed at some universities,
even if they failed their tests. I have had personal experience of this. I failed several students, later I found out they had passed. The admin staff tasked with data entry had changed their scores.

That's why many Chinese universities are rated lowly on the world stage. What's more, Chinese students attending joke universities in China tend to have entitlement mentalities - they expect to graduate regardless of poor academic performance. However, some go abroad to study, but if they can't pass their exams they'll be sent down. That is as it should be.
