Advantages of studying the same major. Because in the undergraduate stage, you have accumulated experience in related majors, then in the postgraduate stage, you can continue to go deep into this field and study one of them. For example, if you study computer-related things yourself, at most, when you are an undergraduate, your use of computer-related software-related programming languages does not involve a deep direction, but when you are a graduate, you can continue to deepen in a certain direction, such as computer vision, natural language processing and so on. Both enterprises and universities need several people who are proficient in a certain direction. If you really don't seem interested in this science, you can consider changing your major. You can also cross the exam when you take the postgraduate entrance examination, which is also a way to change your major. However, it should be noted that some schools do not support cross-majors. So you should also pay attention to collecting information before the exam. It takes a lot of time and energy to participate in interdisciplinary examinations and research. If you really don't like this major, it's also a good choice. After all, this is also an opportunity. The opportunity is just around the corner, so try to seize it. I hope the above two points can help you ~
