Those who can take a double degree, that is, the second major, start to register when you are in the first half of the semester, and start classes when you are a sophomore, but it will be very busy. Basically, I have to take the second major class on weekends. See if you are not interested in learning. It's sad that you have to make up the exam if you fail. Moreover, there are not many courses in the second major, and there may not be anything you like. If you really don't like your major, you can spend a lot of money to change your major in advance. If you don't want to spend too much money, you can change your major in your sophomore year. As long as your freshman course is not miserable, the counselor is also very accommodating, and you can change it without spending money. Just learn from the freshman year. . . What is your major? I hope it can be adopted.
