If it is 3 plus 1, that is, the junior year is exchanged to Japan for one year, and after one year, he returns to China to continue his senior year. In this general school, he must return to China, and the school will give him a year's tuition in Japan.

If it is 2 plus 2, that is, junior and senior students are in Japan, and then they graduate and get diplomas from two schools, and they have to pay their own tuition fees at both ends of Japan.

Maybe there are differences between schools,

You have to check with the school first, and see if it is stated in the exchange contract that you must return to China after the exchange period expires, so as to see if you will not be given the opportunity to take the exam. You need to follow the contract, and taking shortcuts will generally affect others. ..

For example, I heard that after the exchange students arrived in Japan, there was no news directly. ...

In addition, Japanese universities enroll students in summer and autumn, and enrollment in April of the following spring 1 is delayed? Then retake the exam.
