2. The conditions in the southern campus are the best among all campuses, also called the central campus. You will know that the name is excellent, that is, in the suburbs, because it is too big, and other small campuses are in the city.
3. The style of study is very good. Many of the better majors in the school are in the south campus, so the students are better.
There is a computer college in the southern district, and the computer major you mentioned should belong to the computer college.
The School of Computer Science and the School of Mathematics share the same campus. Of course, it's not far. Both of them are in the same campus.
6. Skipping classes, which major to skip, or even going to other campuses are all right, so don't worry. As for the second major, it seems that they are all economics and foreign languages. Never heard of a computer major. Also, the second major is basically to spend money to buy a certificate, but you can't learn the real thing.
7. As for statistics and information and computing science, I really don't know ... I study literature and don't know much about it. I'm from law school, and I'm on your campus. Welcome to Jida and Nanqu, hehe ~ ~! But I think, since it's not your province's enrollment, don't miss him. I believe what you choose is the best, and it is the best to study your major well and spend your college life happily, don't you think?
