The possibility of passing a thesis defense at one time varies from person to person, and depends on many factors, such as the quality of the thesis, the level of the members of the defense Committee, and the specific arrangement of the defense.

First of all, the quality of the thesis is one of the most important factors affecting the result of defense. If the content, structure, logic and language expression of the paper are good, then it is more likely to perform well in the defense. On the contrary, if the quality of the paper is poor, there is a greater possibility of problems in the defense, and it may even fail to pass the defense.

Secondly, the level of the members of the defense Committee is also one of the factors that affect the defense results. If the members of the defense committee have a high academic level and professional knowledge, their evaluation of the paper and the depth and breadth of the questions will be higher, and the respondents need to be fully prepared to answer satisfactory answers.

Finally, the specific arrangement of the defense will also have an impact on the defense results. If there is enough time for defense and the members of the defense Committee have enough time to read and discuss the paper carefully, then the respondent may pass the defense more easily. On the contrary, if the defense time is tight and the members of the defense Committee do not have enough time to read and discuss the paper carefully, then the respondent may encounter more problems and even fail to pass the defense.

In a word, the possibility of passing the thesis defense at one time depends on many factors. For an author who is well prepared, fully grasped and has excellent paper quality, the defense may be a chance to pass the test smoothly.
