The basic courses in our college are basically in the big classroom, starting from 200 to 300 students, and blackboard writing is very common in the classroom of mathematics college. Therefore, if you want to get a better listening experience and master the content in class, you basically need to sit in the front row. Don't say that you can't see the blackboard clearly in the back row, even the teacher's voice may not be clear.
Then everyone basically had to take a seat, and the teaching building explicitly prohibited taking a seat in advance for the night, so everyone got up early that day to take a seat. Because a classroom may have several classes a day and different students from different colleges take different professional classes, books that occupy each professional class on this day will be piled up on each seat. Basically, you can know how many specialized courses there are in this classroom by reading a few books in each seat.
The first class in the morning starts at eight. I still remember the first day of my freshman year, when class started at ten in the morning. I went at nine o'clock and thought it was early enough. As a result, there is no room in the first half of the classroom. Later I found out that I was too young. From then on, I always sit at 7: 30, regardless of the class at eight o'clock or the class at ten o'clock.
Later, I slowly found that I couldn't catch up with the front row at 7: 30. Everyone wants to sit in the front row, so one gets up earlier than the other. I observed the rule and found that most students arrived at the classroom around 7: 20, and then I arrived at the classroom a little earlier than this time, 7:00 10.
A few weeks later, I found that it was not enough to come at 7: 00, 10, and then advanced it to 6: 50. In the past week or two, it seems that others have come earlier and earlier, reaching 6: 20 in advance.
The teaching building opens at 6 every morning. In the end, the situation became less than 6 o'clock, and everyone was stuck under the teaching building waiting for the uncle to open the door. As soon as uncle opened the door, he sprinted all the way to the classroom to put down his book and occupied a seat. All the people left under the teaching building are not for the class at 8: 00 in the morning. No matter whether the professional class to be occupied is 8 o'clock, 10 o'clock, 2 o'clock in the afternoon or even 6: 30 in the evening, everyone rushes under the teaching building early in the morning just to occupy the seats for that day. At that time, in order to occupy the front row, I set myself an alarm clock at 5: 20, 10 to get up, 10 to wash, 10 to ride to the teaching building, and finally 10 to stay under the teaching building.
The end result is that everyone's experience is terrible. Although I personally think this has caused a great waste of time efficiency, it is at least fair, fairer than occupying seats all night, so this tradition of occupying seats has been handed down.
But being fair doesn't mean being right. This is not the same thing as insurance research. There are only so many places for postgraduate research, and there must be a screening mechanism, but the problem of seat occupation can be completely solved by the school. Fundamentally speaking, I don't think professional courses should be taught in large classes with two or three hundred students, and the effect is basically equivalent to nothing. If the school can't afford so many teachers, it can at least set up some real-time projection screens in the classroom and help the teachers with portable microphones. As long as it can improve the listening experience in the back row, whoever is full and has nothing to do will run to the bottom of the teaching building to occupy a seat before six o'clock every day.
What about in today's universities? You can get out of anything. In addition to the inevitable core problem of limited resources, you can think about how many things could have been solved at the school level, pushing the pressure on students abruptly, causing unnecessary involution.
