The school has stipulated the conditions for changing majors. Just meet this condition. Generally, it can be changed within the number of majors, depending on your student handbook. The school will inform you when the freshman year is over. Please pay attention to the college and ask. Don't miss time. If you meet the requirements, fill out the application form, and that's it. You can't transfer until the end of your freshman year, and the application is the end of your freshman year, because it depends on whether your freshman year has reached the top of your major.
