Before and After Submission
Before submission focus on getting your research completed and your thesis finished.
After submission focus on getting your confidence raised for the viva through a little preparation.
Before submission you don’t need to prepare for your viva.
After submission you don’t need to second-guess and nitpick details in your work.
Before submission you’re on track to pass your viva.
After submission you’re on track to pass your viva.
The definition of survive is manage to keep going in difficult circumstances. It applies to the whole PhD as much as it does to the viva.
Before submission? Keep going.
After submission? Keep going.
