The key universities in developed areas are more difficult to take the exam, especially the 985/2 1 1 university. The double non-university is relatively easier to take the exam, while Sun Yat-sen University is located in Guangdong, belonging to 21/985 university, so it is relatively difficult to take the postgraduate entrance examination. Shanda is very strong, and the quality of students is generally good. Most of them come from famous schools such as 985, 2 1 1, and their competitors are relatively strong. Students with the same academic level should pay attention to the requirements: not only to publish papers, but also to sign the top two, which is beyond the reach of ordinary junior college students. There are many graduate students in Sun Yat-sen University, and there are few places in each major. Taking the management science of Sun Yat-sen University as an example, the overall number of masters of management science is single digits, and the majority of them are exempt from exams. For example, social security and local capital do not enroll students for 20 years, and the risk of enrollment in education economy and management is relatively large. The enrollment ratio is 10+: 1, which is more difficult and more competitive. Generally speaking, the enrollment ratio of management classes is very high.
