Today, I am going to tell you what I wish every candidate knew before they sat down across from me, because most of what you have been told about viva preparation is either vague or wrong.

The viva is not a test of whether you got everything right.
It is a test of whether you can defend what you chose.
That is a completely different thing, and understanding the difference will change how you prepare.
I have examined over forty-five theses and I can tell you that those who struggle are the ones who cannot explain why they did what they did.
Nobody teaches you how to handle that.
Your supervisor tells you to "prepare for the viva" and leaves you to guess what that actually means.
So here are the fifteen rules I have learned from the other side of the table.

The Research Insider
One insider strategy per week to complete your PhD or DBA on time, use AI responsibly, and navigate the academic system with confidence. 230,000+ researchers follow my work on LinkedIn. 10,000+ subscribe to this newsletter. Here's why. Whether you're a full-time researcher or a working professional doing a doctorate alongside your career, the system wasn't built for you. Universities teach methodology. They don't teach you how to actually finish. Every Wednesday, I share one technique from the examiner's side of the table. The things I've learned from examining 45+ PhD theses, supervising 30+ researchers to completion, and mentoring working professionals through doctorates they were told they couldn't do while working. All in under 3 minutes. AI is changing research fast. I've tested 12+ tools with doctoral students and I train universities on responsible AI use. I'll show you what works, what makes things up, and how to use these tools without putting your integrity at risk. My followers call me their virtual mentor. This newsletter is where that mentoring goes deeper. No fluff. No jargon. Just the strategies I use with my own mentees, in your inbox every Wednesday.
