It was not revealed before the exam. After investigation, the student entered this post before the exam, but he did not post this post, but in this occupied post, and then a bug appeared in it. After the exam, he copied the content of the exam topic into that post and sent it out like this. The time shown in this way is the time when he entered this post before the exam, so it gives everyone the impression that he has already posted this post before the exam.
As for the seriousness of the matter, if students cheat, it is very serious. After investigation, the student did not collude with the invigilator, so it is obvious that it is very likely that the student put his mobile phone in the examination room before the exam, so as to pass the security check safely and enter the examination room and cheat with his mobile phone.
Generally speaking, in the face of these things, our examination institute of the Ministry of Education attaches great importance to this situation. In either case, we must not allow it to happen. Once this happens, it will lead to the loss of gold content in this exam and become less fair. So the impact on us is enormous.
