Just look at the website of the School of Mathematics. The School of Mathematics is divided into two majors: information and computational mathematics, basic and applied mathematics, and statistics for senior students. Computational mathematics is a national key discipline. It's good to learn math. In this scientific mathematics, graduate students can easily turn to electronics, information and communication, computers, machinery, mechanics, civil water conservancy, ships, automobiles, aerospace and other engineering disciplines. You can also learn software and so on. If you want to learn economic management, it's easy to take the exam after learning this science math. You only need to consciously study a few elective courses you are interested in at the undergraduate stage to prepare for the postgraduate stage.

Learning mathematics for undergraduates is often the most favorable condition for further study. If you switch to mathematics, you may even achieve your future!
