A committee that questions you like the real one will
Describe your dissertation in two minutes. Then a simulated committee of three examiners works through your methodology, your contribution, and the gaps you were hoping nobody would notice.
The Chair
Runs the room and keeps the session moving. Asks clarifying questions about your scope and contribution, and never lets you dodge.
The Methodologist
Goes after the design: your sample, measures, statistics, and threats to validity. Wants specifics, not hand-waving.
The Outside Examiner
Has no stake in your success. Challenges your novelty, your framing, and the 'so what?' of the whole project.
Harder than a mock with your advisor
Your advisor already knows your work and wants you to pass. Labmates pull their punches. The outside examiner here has no stake in your success and keeps pushing on your contribution until you can justify it. That pressure is the point — it is cheaper to find the holes now than in the room.
Two ways to practice
Full Mock Defense
A 2–3 minute summary, then the committee works through every area of your defense. ~30 exchanges.
Focused Drill
One topic area. 12 questions. Good for drilling a weak spot before a committee meeting or proposal hearing.
Three questions in, you'll know
Start with a free drill. No card required. Pick a mode, describe your dissertation, and the committee starts.
