My friend who is a teacher is upset because the student did not do well in the exam this time. How can I persuade her?

First of all, it is right to affirm the inner irritability of teachers, because only teachers who are responsible for their work and require progress are prone to such anxiety. This is a necessary stage for every teacher to mature. Let this teacher understand this truth.

Secondly, let this teacher ask himself what he can do in such a situation. Try to do it and take a look, because it is more important to do what you can do than to regret alone. This is a good way to relieve anxiety.

Finally, as a friend, I calmly helped her analyze the reasons for her unsatisfactory results: insufficient lesson preparation, insufficient explanation of knowledge points; or failure to review well, lacking pertinence and timeliness.

I hope this helps and wish your friend a good mood.
