In china I can't say for sure if college is easier then abroad. I know in Canada and the Usa (not all schools) it works like this if your GPA falls below 2.5 (roughly 60% average) you are on probation for a semester if you fall below 2.0 (50%) you are failed out of your program. now more competitive programs (law, Medicine, Engineering, and computer sci) have higher minimums. in china as a foreigner paying more then average chinese citizens and being good for a school you likely wont fail regardless of your work
