Ranked according to the average credit product of freshmen throughout the school year. There is an algorithm of credit product in the student handbook. You can take a look, multiply the scores of each course by the total credits/the total credits for the whole year, and then the top three percent of the majors can apply for majors. Of course, if you rank below 3%, you will have the opportunity to change your major, because not everyone wants to change to the top 3%.

If you want to change your major, come on and good luck.
