No master's degree in information management and information system. According to the different research directions of information management, you can apply for management science and engineering. Personally, I don't think it's appropriate for information management to be all these majors, which is why information management undergraduates in colleges and universities don't distinguish between liberal arts students and liberal arts students. We study trust management, and there are scholars around us, which is an interesting phenomenon. Information management and information system is a science major, I personally think. Because I study this major myself, including computer, economy, management, and the basic courses cover all aspects of mathematics. At the same time, management is also a kind of system design. Economics is finance, accounting and so on. Among them, liberal arts account for less. Therefore, when taking the postgraduate entrance examination, students of this major will have to take Math One, which is an obvious science subject. Mathematics I covers the knowledge of high numbers, linear algebra and probability statistics, so it can be said that mathematics I is a difficult subject. Needless to say, the other two basic courses, politics and English, are all the same in the whole country. But it doesn't necessarily depend on the research direction of the school. Some professional courses need to take three courses, such as Beijing University of Posts and Telecommunications (operational research, economics, management), and some just need to take one course, such as Beijing Jiaotong University (management information system). In other words, if you want to take the postgraduate entrance examination, you should look after the school at least in your junior year. Of course, you don't have to choose a good junior, everything is changing. But at least one thing is certain: if you want to take the postgraduate exam in the direction of information management and information system, please be prepared to take the math I exam, that is, when you are a freshman and a sophomore, you should work hard on math. Of course, if you still want to study discrete mathematics, I can say that postgraduate entrance examination is basically unnecessary. Of course, books are Tongji University Edition and Probability Zhejiang University Edition that we often use, as long as we study the textbooks issued by the school at ordinary times. Others, such as library science and information science, are liberal arts majors, and most schools don't take mathematics (with exceptions, of course), so some students majoring in information management and information system can consider this direction if they want to avoid mathematics, but what I want to say is that library science is very different from information science and information management and information system. Although these majors don't take math, information management and information system majors such as library science and introduction to information science have to take math, and some schools even have the requirement of a second foreign language. Of course, there is nothing impossible, and there are not a few students who take cross-disciplinary exams every year. For some students, the postgraduate entrance examination is an opportunity to re-select their major. Therefore, students of information management and information system can consider applying for information management direction such as library science. Of course, in this case, we can also apply for other management and even economics. After all, I have learned everything, at least I have been exposed to it. When we take the postgraduate entrance examination, we just need to reprocess our knowledge. Of course, you should not go too far in your major, for example, it is unrealistic to apply for bioengineering suddenly. Of course, from another point of view, if you are majoring in library science or archival science, you'd better choose this major for postgraduate entrance examination, because the usual teaching downplays the requirements for mathematics, so it is difficult to get into the first major of mathematics. Of course, it is also a good choice to change your major to administrative management. About the choice of school, it is also a troublesome thing. Postgraduate entrance examination is not like college entrance examination. After the exam, you volunteer. Postgraduate entrance examination is to register first and then take the exam. So please think carefully about the school. If your school is good, it is safer to stay in your own school. Generally speaking, it is relatively easy to take the postgraduate exam in your own school. Of course, if you apply to a foreign school, then you will be well informed. Finally, there are students in that school, especially those in specialized courses, who should be clear about the key points of the exam and the direction of the questions. If necessary, you can contact the graduate school of the school you are applying for and ask for the previous postgraduate examination questions of the school. Of course, it's all about money. But this is very important. You'd better have it. At the same time, the teacher's class notes and handouts are generally not available, which depends on his own ability. When to prepare for the postgraduate entrance examination is a bit simple. It's all your business. No one will organize you to take the postgraduate entrance examination, so it depends on your level and the quality of the school. There is no absolute. I advise you, if you take the postgraduate entrance examination, you should start preparing for the basic courses of freshmen and sophomores. Freshmen and sophomores understand the foundation, and it will be easy to review for the postgraduate entrance examination. And you usually pay attention to English learning, whether you pass CET-4 or go abroad, English will always be useful!
