To do research and write a thesis you have to be pretty smart. You must know lots and understand many complicated and complex facts. However, to get ready for your viva you don’t have to do anything especially complicated:
- Make a plan of prep work.
- Do the work.
That plan will involve reading, making notes, rehearsing for the viva and reflecting on your journey, but it doesn’t need lots of steps or interlocking to-do lists and flowcharts.
Just make a plan and do the work.
