How about control science and engineering (automation) in Shanghai University? Is the postgraduate entrance examination difficult? Why is there an adjustment every year? Is there not enough online people? Anyway, Shanghai University is not a famous school in Shanghai, but also 2 1 1. Every year, students are not very good, and better candidates will stare at Jiaotong University, Fudan University, statistics and so on. Only those with average grades who want to study in Shanghai will consider applying to this school. At the same time, Shanghai University has a high score in Zone A, so the number of online users will be less, and it is normal to need to adjust every year.
