Universities have different requirements for classrooms. Our freshman has a fixed self-study classroom. Maybe our school will arrange a fixed study room in freshman year, considering getting to know your classmates as soon as possible, but it's just a self-study classroom. This is not a classroom for class.
The classroom should go to which teaching building and which classroom according to the schedule. There is no fixed study room after freshman year. If you want to study by yourself, you can go to the teaching building near your dormitory. Generally, every teaching building will have its own study room and you can go to the library. As you look for it yourself in the classroom, the teacher won't arrange a seat for you.
The university won't force you to study at night, and no one even asks you to come to class (individual teachers will call the roll, only a few), but don't fail. If you fail too many classes, the counselor will come to you and even advise you to quit school.
If the school is close to home, of course, you can live on campus, so you can still have accommodation. As I said just now, no one will force you to teach yourself.
There will not be too many people in the shared classroom in general public classes. You should learn to sit down early. In particular, university seat occupation is a university problem, especially when preparing for the CET-4 and CET-6 or the final exam. If you slow down, there will be no seats!
You can go to class, eat with the dormitory or eat by yourself. Pay attention to the relationship with the students in the dormitory.
University will make you unforgettable in these years. I hope LZ will cherish it. Having said so much, add a few points!
