At the beginning of a new semester there's a fierce battle among students to register for courses on their universities' websites. Chen Yuewei, a second-year student at Guangdong Peizheng College, says course selection is not an individual battle but requires teamwork. Since the online registration system operates on a 'first-come, first-served' basis, Chen and three of her roommates wake up an hour before the system is available to prepare to 'grab' the courses they desire. 'I type my student ID number and password in a text file beforehand, so once the system opens, I can copy and paste them into it,' she says. The roommates divide up their tasks. Two are responsible for liberal arts courses, and the other two for science courses. 'We listed all the courses the night before, and everyone took responsibility for registering for certain courses. It is much more efficient than working alone,' Chen says. Yan Xiao, a first-year student at South China University of Technology, chooses his courses using software designed by his seniors. It helps him log in on time into the system and speed up his connection, especially when the network slows down because of the large number of students trying to register at the same time. For those who fail to plan ahead, exchanging courses with others is better than nothing, Lin Dongxue, a second-year student at Sun Yat-sen University, says. 'I will discuss with my friends what courses they have registered for and look for opportunities to swap,' she says. 'We have to do the exchange when few people are online. Once my friend withdraws from his course, I must immediately select the course, otherwise it will be taken by others.'
