I was given a good piece of advice by one of my colleagues. He suggested writing a document outlining how you have addressed the comments you were given by the examiners and then submit this with the thesis, so the examiners know exactly what you have done. I was sent a Word document from my examiners with all the amendments I was asked to make, and so under each of their comments I have explained what I have done and where they can find the new material in my thesis. This also strokes the examiner's ego because it shows that you have listened to what they have said and done exactly as you were told. So hopefully they'll be in a good mood when they read your bright, shiny new thesis (up)
