It depends on which country and school you are applying for. Our school's requirements for exchange students are generally not very high. If English is good, even grades are not a problem, as long as you don't hang up too many classes. One of my classmates applied to Providence University in Taiwan Province, and passed quickly. If you apply, try to apply in your freshman and sophomore years. If you apply for full public tuition, the number of places is limited. Generally, those places will be digested internally, but there are still some places that don't have to pay tuition fees and are only responsible for living expenses and accommodation expenses. In this case, the number is more than enough. The number of people explained by the school is actually flexible, and many schools that accept one by two still agree. After all, many foreign universities regard this as a way to instill capital advantages.
In terms of fees, Taiwan Province Province is the cheapest, about 10,000 yuan a year (tuition is free). Twenty thousand in Korea (tuition is free). Australia and Italy are much more expensive, at least 500 euros a month.
Give points, classmate.
