That's the teacher's call. If consistently underperform pupil once underperformed less he/she may even get praised. On the other hand. If a top 3 pupil ranked 10 once, he/she may receive some shaming. Different teachers have different styles And of course. Some teachers won't shame pupils at all. But the rankings are always public. No one can change that.
