My college is 1 1. If you want to change your major after entering school, you must change your major in your sophomore year. Freshman is not allowed. And if it doesn't matter, it's basically hard to rely on yourself. Think about it, you can't just change majors, and the scores of each major are different. If you enter the school with the lowest score and then change your major, it will be a mess. So I suggest you choose that major when you apply for the exam, and don't want to transfer in the future.
