You Can Have It All
You don’t get to choose or refuse questions. You don’t decide how long your viva will be. You can’t arrange the tables just so. You don’t technically get to choose your examiners.
You can’t dismiss a rule or regulation that sounds unfair. You can’t say no to corrections. You can’t change the scope or the process. You can’t decide when it’s over.
All of the above are true, but what do they matter?
You can succeed like most candidates do.
You can do the work before and during the viva. You can show up ready. You can focus on the expectations that make a difference and leave aside all of the above.
You can have everything that does matter by checking a few things out, asking the right questions and preparing. Do what you need to and you can have it all at the viva.
