Every university can change majors, usually with a grade point. Take my school as an example. If you want to change your major, you need an average grade point average of 3.5 or above (the schools with grade points of 5 or 4 are different accordingly). You can understand GPA as an average score. It is true that every school can transfer, but considering that everyone wants to transfer to a good major in their own school, the competition for changing majors is fierce, which is not as simple as many people think.
