Hello, there are generally two ways to change majors in Nantong University. First, after you are admitted, it will take about100000 to change your major. It seems that it will cost 1.5 million this year. If you have enough money, basically no problem. Second, when you have completed your major for one year, that is, next semester, you can apply to the college to change your major, which is generally successful. It doesn't matter even if you fail in freshman year. If your major also needs to study the courses you failed, then you should study again and pass. If you don't need this course in your major, you have nothing to do. I have a classmate who failed several courses in his freshman year and changed his major.
