There are many students visiting abroad and going to European and American universities, and English communication ability is the necessary foundation. Most courses are required to pass English-related professional tests or meet certain standards of CET-4 and CET-6. Some academic visiting projects will also have corresponding professional requirements, and a few projects will also require a certain professional knowledge base.
Perhaps many college students are not sure whether they meet the requirements of foreign exchange programs. I suggest you go to official website, SAF, inquire about the contents of relevant exchange programs, and compare them with your own conditions. You can also seek the help of SAF instructors online.
