You can't change your major when reporting, unless you have found a relationship before. You can apply in the first half of the semester. You should ask the counselor about the specific procedure. I got better grades in my freshman year. I'd better pass Band 4. Then you can switch to any major you want. This should be evaluated by the counselor of the major you want to study. Generally, universities pay attention to grades, but if you change your department and have to move to a dormitory or something, you'd better live with your classmates, so you'll know what will happen. By the way, the school of chemical engineering in our school is good, followed by the school of mechanical information. Liberal arts is not so good. After all, this is a science and engineering college.
