I think the big reason is that the difference between university and high school is still obvious; University is a relatively free place, and you can arrange almost all your spare time except class time. Moreover, the administrative courses in universities are not so obvious, and sometimes even several classes have classes together; Moreover, there is more than one classroom in each class, and some even have two-thirds different classroom arrangements. If there are fixed seats, it is also an inconvenience for students in class.

But high school is different. We have fixed courses, fixed classes and fixed classrooms. It can be said that everything is fixed. Therefore, fixed seats will not have a great impact on students. What's more, even if the seats are fixed, the high school almost changes seats at the rhythm of 1/ half a month. To tell the truth, almost all high school students who want to learn or have good grades will sit in the front row, while those who don't learn much or have relatively poor grades will be behind.

The difference between universities and high schools determines that universities do not have a fixed role like high schools. University is a process of paying attention to self-study, which requires students to have self-control, rather than the supervision of teachers all the time. What's more, even if you want to have a teacher to supervise you in the university, it is almost impossible. A teacher with a little conscience will only give you a little reminder in class. Whether they study after class has nothing to do with them. There is no fixed seat, so you can adjust it according to your own progress. Some students need the teacher's explanation more, so they will sit in the front row; And if they want to teach themselves more, the teacher will not impose more restrictions. As long as you don't affect the progress of the course, you can also choose to sit in the middle or in the back seat.
