Studying abroad 360, Xue Yan introduced that no matter how many courses you have studied, you should fill out the application form first and apply for the major you want to apply for. Then the second step is to make a document of the official courses (course descriptions) of the courses you have studied and the scores you got when you studied, and send them to the school you want to apply for together with your application form. Then the new school you want to apply for will compare your course description and your grades with the courses they teach. If a course or several courses are found to be basically the same, it is considered free.
