The difficulty is relatively higher than that of Gao Xian Jiaotong University. First of all, Xi Jiaotong University is one of the top institutions of higher learning in China. It belongs to the 2 1 1 Project and the 985 Project National Key Construction University, with abundant teachers and excellent teaching quality. Secondly, as a high-level research university, Xi Jiaotong University requires very high comprehensive quality of candidates, which requires not only solid professional knowledge and research ability, but also the improvement of basic quality such as English. In addition, the number of graduate students in Xi Jiaotong University is small, the number of students enrolled each year is very limited, and the competition is fierce. Candidates need to pass written examination, interview, re-examination and other links before they can enter this school for postgraduate study. The written test includes comprehensive quality and specialized courses, and the postgraduate entrance examination is quite difficult, which largely depends on the content and scope of the test. Postgraduate entrance examination subjects include politics, English, mathematics, specialized courses and so on, involving extensive and in-depth knowledge. For non-science students, mathematics and specialized courses are great challenges. Therefore, candidates must make more efforts in preparing for the postgraduate entrance examination. There are no advantages and shortcuts. The only thing that can be changed is your own efforts. To sum up, the postgraduate entrance examination of Xi Jiaotong University is difficult, but for all candidates, the difficulty is not absolute. Candidates' personal factors, professional background, learning situation and other aspects will affect their performance and opportunities in the postgraduate entrance examination. Candidates need to make a study plan that suits them according to their own situation, and make full preparations before the exam to ensure their best preparation.
