The study room is ok. There are many people at the end of the term, and someone will bring food in. Some people can talk, just like bees buzzing. Generally speaking, it's ok, except that this study room is closed occasionally, such as now.
Of course, choose the teaching building for self-study. It's not hot with a fan. The disadvantage is the teacher's buzz in class and the students' voice in the corridor during recess. Also, if someone comes to class halfway, they have to move. The teaching building will be locked on weekends, but when the door is not locked, the whole classroom in the teaching building will choose ducks at will.
