I think it is very necessary to study exchange students in domestic universities. Here I suggest that if you can get an exchange student's learning opportunity, you must seize this opportunity. It is difficult to determine this date. Besides, being an exchange student has many advantages. The biggest advantage is that although you can study for four years as an alternative nutrition in college, you will have two degree certificates when you fall down. One is that you applied for the university of your choice in the college entrance examination, and the other is the degree certificate of the school where you went as an exchange student. Stay and think. In the same four years, you have two degree certificates, one more than others. That's a great feeling. The second is that if you can become an exchange student, you must be an excellent student in your major. As exchange students, they usually go to some better schools than themselves, so that they can get more good educational resources. For example, the teachers who give lectures to you are all professors. Their educational style is definitely better than that of your school, and the students around you have become more qualified. You can gain the influence around them invisibly and then learn from them. In this way, you can improve yourself in a short time. Maybe you are the first major in your university. If you have no competitors, you have no desire to compete. If you go to a better university as an exchange student, there will be more excellent people as your role models. You will definitely study harder, so that you can improve yourself better. Therefore, it is better to go to university as an exchange student. No matter at home or abroad, there are many benefits. So if you have the opportunity to be an exchange student, you must go. Don't waste this opportunity.
