When I did my PhD there was very little help available for viva candidates. Now there is help everywhere.
There are scores of advice articles for the viva and probably hundreds of blog posts about personal experiences – you can find a link to some of them here!
Universities have staff who are there to answer questions, academics with experience who can tell you what’s what and resources to help get ready for the viva – it’s worth checking out what’s available at your institution!
There is a super-abundance of help for the viva out there. A wealth of information, ideas and advice that can be accessed by any PhD candidate who wants to know what the viva is about and what they can do to be ready.
So: what will you do to get ready?
Because now all of this help is out there, the only thing stopping you being ready is your decision about what you will do.
