A Room Where You Can't Leave Unless You Get a Score of 700 or So

Lu Meng is a high school student. Lu Meng is a high school student who suspects that he is crazy. She just fell asleep while doing math problems in English class. How come she was in an isolated room when she opened her eyes, and the requirement for leaving was to "get a score of 700 or above"? Fortunately, her talkative deskmate also traveled through time together. Even if they die trapped here, they can still be buried together. I wish we could get out of here.
