If you really don't like the major of mathematics, then apply for changing majors as soon as possible, and don't delay your youth. From high school to college, it is normal not to know how to choose a major. Although interest is the best teacher, since it doesn't suit you, you should leave. Don't spend four years cultivating your so-called interest. Of course, there are special circumstances. If you change your major, you won't start from freshman year. Then ask yourself to spend more time on self-study. .
