At present, most colleges and universities arrange students to choose the courses they need to take in the next semester at the end of the semester, and with the popularization of campus networks, course selection is conducted online.
Therefore, students will choose courses in the educational administration system of their respective universities. Students generally need to log in to the system, choose courses and draw lots. Problems in any of the three steps will cause students not to choose courses.
In the case of limited number of courses, all students enter the elective educational system at the same time, watch a course, refresh the number of courses all the time, and then choose. In the case of limited network recognition ability, it sometimes leads to the collapse of the educational administration system, and even directly leads to students being forced to quit the system, resulting in most students not choosing the elective courses they need at this time.
Because all students log on to the same website at the same time, it is inevitable that the network will be congested, so a class-grabbing war broke out.
Extended data:
College courses are optional. For example, there may be more than a dozen teachers taking this course at the same time. You have to choose a teacher on the computer and go to class with him. But a good teacher usually chooses many people. So choose as early as possible (that is, grab classes), and if you choose late, you won't get in, because the number of people in a classroom is fixed (for example, 50 people, those who choose 5 1 can't get in).

The survey found that students "grab classes" concentrated on popular courses, and some waited for three years to grab their favorite elective courses; There are also "unfortunate" failures, waiting for the by-election of the course. Faced with such a "tight" course selection situation, services such as "grabbing classes on behalf of others" and "taking classes on behalf of others" began to appear on Taobao, and the price of each course was even as high as 100 yuan.
Some colleges and universities have begun to take corresponding measures to solve the problems of slow course selection and shortage of popular courses, which are reflected in the high price of Taobao.
Now many colleges and universities will subdivide elective courses into four or five categories. When students choose courses, they must cover all kinds of courses, and each course must have enough corresponding credits. Most colleges and universities will regularly upgrade the course selection system and campus network; Before freshmen choose courses, colleges and universities will give detailed guidance on course selection, and some colleges and universities will also ask teachers and previous students to give guidance on course selection for freshmen.
Taking Peking University as an example, the school has taken corresponding measures in all aspects of students' course selection to alleviate the phenomenon that popular courses are in short supply. On the one hand, appropriately increase the number of courses and the number of participants. "The school has added some new courses to disperse hot spots and ease the pressure of popular courses."
A teacher from the Peking University Academic Affairs Office said, "We will also consider the situation of all parties and adjust the upper limit of the number of people in some popular courses." On the other hand, the Academic Affairs Office will issue 99 "willingness points" to each student every semester, and students can allocate "willingness points" to each course in the pre-selection stage of course selection. According to reports, the pre-selection stage adopts the method of probability lottery. The more "willingness points" students put into a course, the greater the probability of choosing this course.
