What you want to ask is which is the earlier time for graduate students or college students to defend their papers? The defense time of graduate thesis is similar to that of university thesis.

Postgraduate graduation defense is usually in June. Postgraduate graduation thesis is generally issued for blind review at the end of April or early May, and returned to blind review in the middle and late May. After passing the blind test, candidates need to revise their graduation thesis according to the blind test opinions. Generally, I will take part in the graduate graduation defense of our school in early June.

The defense time of undergraduate thesis is generally from May to June, and the defense time of different schools is slightly different. Many schools arrange the time for thesis defense at the end of May. After the defense, teachers and students celebrate together. When the graduation certificate is issued smoothly, the students' activities on the university campus are basically over. If you can't pass the defense within the specified time, the graduation of undergraduate students will be affected.
