The only way is to go to the academic affairs office of your school and tell the teachers there that you are going abroad and want to retake some subjects that have not failed before, which has met the requirements of others. At this time, you will be asked to spend money to retake the exam, or some schools are free, depending on your school policy. The second interview can cover the original results, and the final report card will not be displayed, so it doesn't matter. But if you fail at first, the maximum will be 60, which is equivalent to being scrapped, so you can't fail anyway!
By the way, any form of change to the report card is called fraud. Whether it is to change grades, delete subjects, or change the course semester, it is equally serious. This thing can be found from the outside, so if you change your score, you can only expect the other school not to check your score, otherwise it will be found out.
