In Untiled State, change classes after class ends. This is normal for students here, but Thai students are different. Thai students will remain in the same class from first grade until the end of high school. The class might be moved to another building or room, but that only happens every two or three years. So, all students will sit in the classroom waiting for teachers to come in, instead of leaving like in American schools. Even during gym class, teachers have to come to the classroom to take students to the playground, and after the end of the lesson they have to bring all the students back. This is also a way for Thai students to have a strong friendship after graduation. However, American school is more fun because students go into different rooms and meet different people. After class ends, students run to the other room. They go to their teacher rather than going to his teacher
