What I said above is not alarmist, because I recently saw a news that some schoolmasters began to sell their postgraduate entrance examination materials at high prices. Such a thing seems to be nothing, and most people think it is normal, but in fact it is a blasphemy against learning and a betrayal of knowledge. Such behavior has a negative impact on society and psychological harm to students.
People who study well can make money by their own experience and knowledge, but it depends on what method you use. You can be a tutor, or you can communicate with others reasonably to make money through these tutoring methods. However, it is immoral for some students who learn well to use their own postgraduate materials to clearly mark the price, not to mention that such postgraduate materials are not necessarily useful.
We know that a person's success is difficult to replicate, let alone the national examination. If a candidate learns the so-called Xueba materials without any help at all, then the student will be greatly hit. We know that every year's national examination has different topics, and every examination is a new beginning. It can be said that no matter how hard the so-called schoolmaster works, his grades are likely to be poor.
So I think that the so-called Xueba sells its own materials. The first is opposition, because it is cheating on other students. The examination has its own rules, but it is not a postgraduate entrance examination material that can completely help candidates. I am a graduate student myself, but I have never read the exam materials of Xueba. My experience is that every start is different. Only by studying hard can I really succeed. Therefore, Xueba sells its own postgraduate materials at a high price. My opinion is that it must be stopped!
