1. It's not a big problem if you don't change your grades, but if you change your grades, the university will know that the consequences are very serious. . .

2. Preparatory courses are the same everywhere. Since you have to study hard, it really makes no difference. Don't listen to those shortcuts when you go to college. If you want to enter these two universities, it is important to meet the standards in alevel and language. Unless you have a high talent in a certain course for them to choose you, your grades are still the last word. However, since you have attended preparatory classes in two universities, your chances are definitely higher than those in other schools.

3. If it is a preparatory course, it is not recommended to apply for a language class. This is really just a waste of money and time, and I have a deep understanding of it. . . As long as you work hard, 1 year is enough. If you decide to study, 1 year language time. Accommodation is different in every educational institution, but of course it is better to live by yourself, or is it a waste of youth after finishing the preparatory course? . . .
