What if the course selection system collapses?
1, by changing browsers.
Because the internet speed of different students in different schools may be different, it is suggested to use different browsers to grab classes. You can save your personal account number and password in the course selection system, and then collect them in your browser's favorites. Then copy and paste the personal account password into the favorites, and log in to other browsers.
For example, Sogou browser, Google browser, cool dog browser and so on. Or download the UC browser and log in to the alternate website of the course selection system, and you can log in, which can solve the problem that the system can't squeeze in.
2. go to the merchant to grab it.
If you can't compete with others at school, or you don't enter the course selection system, you will be excluded. Can you find someone to replace the class robbery? Enter your personal account password and the number of the selected course. Then submit a certain fee to the merchant, and you can grab your favorite course.
Because there are too many students in the school and the student base is too large when grabbing classes, finding a substitute can greatly reduce the consumption of time and energy. It is precisely because of the collapse of the system that students have some courses that universities can't grab in four years, which is very unfavorable for credit study.
