Hi Angelina,
I actually have no idea, my ext2 teacher is away for the holidays so there's no way to ask him. I'll definitely find out because that'd be extremely helpful. Is there anything else that I could do additionally to enhance my presentation? I also heard that sometimes they ask questions that aren't on the document we were given, does this happen or if it happens is it just for clarification? Also, how much of your viva was written down on palm cards/elaborated on the spot?
Thanks 
Hey, meerae!
Definitely check to see if having a PowerPoint is allowed because it was incredibly helpful. Rather than what more you could do to enhance it, I would actually recommend reducing your content on the PowerPoint to the main points you have and simply leave dot points on them. You could instead have images to make the slides more interesting and incorporate quotes from any critics or research you have done already to show where your ideas are coming from. Less is certainly more with PowerPoint presentations.
I only had the same number of palm cards as I did with my slides and the same dot points there on my cards. I did this so I was able to use them as prompters and was able to speak off them without looking at my slides

It takes a lot of practice to speak on the spot which is why I would advise you to practise delivering your Viva to your family and peers. You can rehearse speaking off the top of your head in a more comfortable setting that way

As for impromptu questions, I got asked two questions on the spot but I know some of my other classmates did not. This is usually just for clarification but if you get a question like mine about where you may intend to take a certain idea, take a breath, think about what you want to honestly tell them and be confident in your response. The markers will appreciate that you have processed their question and given a truthful answer, rather than one that is rehearsed and regurgitated

Once again, rehearsing your Viva in front of people you are comfortable is beneficial. They can ask you any questions they may have and you can practise responding to them. This can simulate the experience of the Viva and prepare you for that possibility.
I hope this helps and let me know if you have any other questions. Good luck with it and do tell us how it goes

Angelina
