I have only been there once. I don't know exactly how many study rooms there are, but there should be many.

If it's normal, there should be few people. If it's weekends or winter and summer vacations, there will be many students.

Many students went early in the morning, fearing that there was no room, but I didn't seem to get a ticket when I went last time.

Because there are many people who go to the toilet to buy food and water, the administrator doesn't know which one bought the ticket and which one didn't, and students usually stay for one day, so the management will be relaxed.
