It is right to do that I can't see it and continue or it is right to punish the student, e.g. Confiscating the test and giving it a five may be a trivial question, but what is the acceptable response to the teacher's copying, because my accompanying teacher preferred not to see it and continued to correct previous papers, which did not seem right to me.
Maybe it's a trivial question, but what's the acceptable response to copying on the part of the teacher?
