How to complain about the poor teaching level of the examination and compilation teacher?

You can complain to the examination institution, but if you want to complain to an official institution like the Education Bureau, you will probably not succeed.

Do your homework in advance in the preparation class, so as not to choose a poor teacher.

Examination compilation generally refers to the teacher's preparation for the exam. The teacher preparation exam belongs to a kind of teacher recruitment exam.
