I have my viva in a week and a half and I've just found a mistake in my thesis. It isn't a major mistake, as it's in the explanation of a method used, and doesn't make my results invalid. However it does make me look like I don't understand the method properly, which I do. Do you think this will cause a major problem in the viva? Or will the fact that I've noticed the mistake now and will be able to correct my error if it's brought up in the viva go in my favour? Thanks for any advice, I'm really nervous!!
