The first reason is said on the second floor. This year, our schoolmates really took several questions (specialized courses) the same as ours, exactly the same!

The second reason is that the test paper should be sent to the academic affairs office together with the score after revision to avoid problems such as moisture in the score. Then it should be put on record, and all superiors should check it (the content of the inspection is the same as that of the academic affairs office, which is a spot check. ) our school was checked when it was appraised, saying that all the papers of that year were taken out.

And as long as you ask, the teacher seems to let you see it, and there are people watching it here. But before sending it away, that is, within one day after the exam.
