The college class is ok, just blend in. There is no class, you can study in any room.

Recommend Polytechnic University, Polytechnic College and Engineering College. . . .

If you must have a library. Then go to the city map, next to the clothing city. You don't need cards. If you study at home, you can register with your ID card. There are desks and chairs on the second floor if you don't enter the house. Just go straight up. . . .
