The defense time of papers in different universities is different, and the defense time of different majors in the same university is also very different. Postgraduate thesis defense needs to pass blind examination, which can be divided into city blindness and school blindness. Generally speaking, the person who is selected as blind in the city is more tragic, and the quality of the paper should be higher. The corresponding reply time of the city blind is earlier than that of the ordinary students. Since the master students leave school at the end of June and the beginning of July, during this period, the students will have a lot of things to deal with, so the defense time will be fully completed in May. For the students of Jiaotong University, it is said through the grapevine that many people have already completed their defense in that year and will get their diplomas in April, so I suggest you ask teachers and students (seniors and the like) about the arrangement of defense time. For China Normal University, the defense is in April.
