In principle, you can change your major, but you can't change it until one year later. In fact, it doesn't matter if you wait a year, because in the first year, almost everyone studied the same, and the key grades were better. I am a student of Grade 04 in School of Economics and Management. Five or six students in our major are transferred from agriculture and forestry. Of course, you'd better ask the school teacher, I hope it will help you.
