大学老师不满学生给差评 给全班150人打零分

Teachers have to remember: student is their customers, and customer is the god!😂

This happened to me when I studied in US. The final result is the school forced the teacher to review his marks for all the students in the class and didn't renew this teacher's contract after the term. And it will be difficult for him to look for another teaching job with the bad review from the school board.
