1. You can choose a double degree or minor in another major during your undergraduate course. Take an English major as an example. He is very interested in American finance or accounting. He can choose to minor in finance or accounting in his sophomore or junior year. When applying in the future, American universities are equivalent to having relevant backgrounds. As long as he can prove on his report card that he has really studied these courses, it is equivalent to having relevant background. Minoring in the second major is really very important for students who plan to change majors in the future, and it should be said that it is the most effective way.
2. For those students who have entered junior year and have not minored in any major, there is still room for change, that is, to improve their background through internship or reading a lot of relevant books. For example, students who originally studied media want to study statistics or finance in Fine Arts, so they can use their junior summer vacation to do some internship experience, such as going to banks, securities companies or related companies, and decide whether the major they want to study in the future is the career development direction after graduation.
3. You can choose to take GRE SUB (GRE single test), which is a good opportunity to prove yourself. For example, my major was automation, and I want to study computer science as a graduate student in the United States. Although automation major has also taken some basic computer courses, the courses are far from meeting the requirements of applying for computer major in the United States. At this time, students who change majors can take the GRE computer subtest to prove that they are in the computer field. If the score can be above 90%, it will be an excellent result, which will play an important role in applying for computer major in the future.
