Viva Omens
Some things just are, in life and in the viva,
Typos don’t indicate that you’ll face stern questions or tough corrections.
Silence in the viva doesn’t mean that anything is wrong.
If you pause to think then your examiners don’t expect you have a problem.
And if your examiners are subject experts or take a long time to discuss something or if they have done research in something different you are no more likely to face a bad experience.
Some things just are. Typos are simply missed, silence happens when people think and pause. Examiners need to be experienced and can take their time.
None of these are omens of a bad viva or a bad outcome.
