Time is not uniform throughout the country. The time is determined by the teaching and research section of our school according to the specialty particularity, which is generally about 5 to 15 minutes.

Generally speaking, the defense is divided into four parts: telling one's own thesis, teachers' questions, students' answers and teachers' grading. Some defense is to ask several questions at a time, so you can go down and prepare for a few minutes and then come back to answer. Some defense is to answer questions on demand, which will be more difficult.
