Meten is a large Chain school a copy of a copy i think a copy of UN or Aston and charges as much as WEBI

the scores are not filled out by students mostly but by study advisors who fix the scoring at the end of the month using students accounts

students are not interested in this 1-5 scoring thing and know teachers can see it, every teachers score is high anyway like 4.8 or 4.9 out of 5
and it takes just one low score from one student or SA at 1159 on the last day of the month to fix the monthly bonus

usually to give a Chinese teacher the monthly bonus of 500 rmb or a teacher in a relationship with management or stop a teacher who complained about something

Even the head office knows this and changed the system so local managers cannot see or change it. now its done by wechat or QQ. But local managers who are just messengers still try to bully and tell lies about anyone who doesn't bow to their stupid ways
