You can change your major, whether you are a junior college or an undergraduate. Before entering junior college, teachers will listen to students' opinions and then change majors. It is more convenient to change majors at this time. However, when you change majors during your undergraduate study, you usually prepare for the exam in the summer vacation of your freshman year, and then you can successfully change majors in your sophomore year. At this time, you need to take the exam and change your major. The content and subjects of the exam should be determined according to the requirements of your major, so you should take an active part in the major transfer exam to find out which major you can transfer to. However, the number of places in this exam is limited, and sometimes the number of applicants is relatively large, especially those popular majors. In this case, you will fail to pass the exam, but don't worry too much if you really fail. After all, I have a strong ability of self-study in college. I suggest that I keep a good grade point in college, and then learn more about the major I want to study. You can also change your major after graduation.
Choose a suitable major, but candidates must consider what they really want when choosing a major. Some students have strong learning ability. Moreover, I especially like to study my major of interest. At this time, you don't have to consider the employment prospects. As long as I'm interested, I'm sure I can make scientific research achievements. Even if you don't work in a company, you can find a good job in a research institute or school in the future, but if you still want to focus on employment, you want to go to a big company to get a higher salary level. Then it is suggested to choose some popular majors, such as computer major, finance-related major and law-related major. In this way, you can get a better job, and then you can meet the job opportunities of a good company, so you still have to think clearly about the future development path.
