You can just fake it if you can get a campus map somewhere. Essentially, it’s a village, except instead of work/commercial place, it’s a study/educational place. Admin building is like Government. Student Center is like Commercial zone. Dorms are Residential. Different buildings for classes teach different disciplines: Math, Engineering, Biology, Social, etc.
There’s also special function buildings such as Gym, and Performance Arts and Library.
But you want some cultures on Campus, so know that classes are scheduled, and that you need to arrange your classes accordingly. You don’t have constant classmates except for the same classes. Even students pursuing the same degree may not attend the same class, unless they coordinate. Dorms/Roommates don’t necessarily attend the same classes either.
The most memorable event on college campus lately, you can research “Evergreen State College” which I’m sure is so famous, just about everyone knows about it. Plenty of coverage, albeit small sections, about students behavior on that one.
