There are three thresholds for entering the computer graduate school of Zhejiang University: passing the exam, re-examination on the computer and re-examination interview. The first two items are hard indicators with no room for manoeuvre. Interview because our teacher is friendly (Zhejiang University's computer culture is "harmony is the key to change"), unless you are too weak, or do something that drives the teacher crazy, or people think you are mentally abnormal, the scores will not be far apart. Finally, the question of whether to recognize people or not. No matter what school or background, everyone will line up according to the overall evaluation results, which is relatively fair. Online students must find a tutor who is willing to accept you before a certain period of time, and sign the admission notice before formal admission. So if you want to achieve your goal, first of all, you should prepare for the unified examination. Passing the exam line is the first step. In another year, the grade A score of PAT (Programmability Test) can directly replace the retest score on the computer. You can take a PAT Grade A exam first, or you can just take the traditional computer exam. The difficulty of the two is the same, but the difference is that PAT has three opportunities, and the pressure during the exam is less. Maybe he will get a high-paying job directly after the exam without going to graduate school. For sophomores, learn solid basic courses, including at least one programming language, data structure and algorithm, computer composition, operating system, computer network and database. This is the smallest set. When I was a junior, I began to think about doing a small extracurricular project, trying to find my own interests. On the other hand, postgraduate entrance examination is not the ultimate goal of your study. What kind of talent you want to be after your student career is a question you should carefully consider.
