First of all, don't lose your mind. Personally, these cheaters have nothing to do with your life. You compete with him only because of his studies. You saw him cheating, but what you didn't see was that there were many things in this society that seemed unfair all the time. There are too many unfair things in society, and you can't maintain fairness on your own. So if you struggle with everything, you will lose your mind and lose your state.
Secondly, don't mind your own business. Everyone should despise such behavior in their hearts. But can we take care of others and tell them not to do so? Do you think that the existence of this phenomenon can be completely contained by one person or several people? The obvious answer is: no.
Finally, be yourself. For the cheater himself, his biggest goal in seeking cheating is to pass such an exam. Everyone in the university knows that it is easy to think about the exam, but it is difficult for you to get high marks. Therefore, I hope everyone can put aside their personal feelings and stand and think about why there is cheating in college. Is it because everyone's academic pressure is actually too great? You said you could talk about one chapter at a time for a week. Then, let you review ten courses a week and give you two courses in CET-4 and CET-6. This deliberate arrangement is really too heavy for college students. So some people will choose to cheat because they are afraid of failure. But as ordinary citizens, can we change? Obviously not, so be yourself, be yourself and ignore others.
