Common thesis defense questions
The questions almost every committee asks, and what a direct answer has to cover.
The room repeats itself
Committees sound specific to a field, but the first twenty minutes of a defense follow a small set of jobs. They want to know what you claim, why the claim needed a study, whether the method can carry it, what you found that you did not expect, and what you will not claim. If you can answer those five without reading from a slide, the later questions are variations.
Write each answer as something you can say in under two minutes. A defense is a conversation with a time limit, not a second copy of the chapter. If the answer needs a table, know which table and what one number on it does the work.
Questions you should be able to answer cold
What is the contribution in one sentence, and who would be wrong if they ignored it? Why this site, sample, archive, or dataset rather than the obvious alternative? What would falsify the main claim? Where is the weakest chapter, and what did you do about it? What did you try that failed and does not appear in the thesis?
Which literatures did you decide not to engage, and why is that a boundary rather than a hole? If a key assumption is false, what part of the result survives? What should the next project measure that you could not? What, concretely, should a reader stop doing if they believe you?
How to practice them
Answer out loud, then write down only the points you skipped. The skipped points are the real practice list. A polished paragraph you have never said aloud tends to collapse when someone interrupts after the first clause.
MockCommittee is built for that second pass. The audit flags claims the committee can pull on. The defense round asks one of them, scores the answer you actually type, and shows a spoken reply to study. It will not hand you a rewritten chapter. The point of the exercise is that you can defend the chapter you already wrote.
MockCommittee will not draft, rewrite, or polish thesis or dissertation prose for you to submit. A stronger answer is a spoken reply you can study aloud. Putting it into the document is academic misconduct.
