It depends on your previous achievements and the competition with your major. Let's just say that the major you want to change is limited by the end of your freshman year. For example, it can accept three people. Six of you enter the competition, and the top three can pass. Moreover, liberal arts students should only transfer to liberal arts and not science. You have to ask the teacher about this. All you can do is try to get higher credits and other scores, and then you will be competitive. Then contact the tutor or something for consultation in time.
