1. Grade inflation.
2. Bell curves so that a certain percentage of students must pass.
3. Student evaluations and students voting by enrolments that discourage tough/realistic marking.
4. Marking of courses is controlled by the teachers of the course. Thus the teachers are in effect assessing themselves.
5. In some countries students who pay full fees are marked easier than those who have government funded places.
Hiring people in IT, I was amazed to find that a high percentage of people who have passed programming courses are totally incapable of writing a working program.
So let us not be too scornful of the Chinese.
