Information management and information system is not only a management major, but also an engineering degree, which should be a very broad major; Apply for graduate students, except information management, computer science and software engineering; But I think, as a girl, it may be more appropriate to apply for statistics. Statistics is a rapidly developing major in recent years, with many new disciplines, such as bioinformatics, financial statistics, big data technology and so on. Most of these majors use computer science as a tool, just in line with your information management major; Moreover, it is easy to find a job after graduation and the working environment is good. As mentioned above, you can ask the teacher for advice; But I think this is more in line with your reality.
