You will probably be conflicted, unless you managed to breeze through with no amendments. Then you will just be smiling so hard you’ll worry your face will hurt tomorrow. That’s good. Keep doing that. Who cares if it hurts tomorrow? It’s worth it.
If you aren’t one of the lucky ones (i.e., you’re most people), then the moment your viva is over is going to bring all sorts of feelings you can’t really classify. You don’t have to classify them. You don’t even have to understand them. Every single thing you feel after the viva is valid. There’s no ‘right way’ to feel afterwards. Some people, even with many amendments, might be absolutely thrilled. Some with only a few amendments might feel awful that they didn’t do better. A lot of that is going to be something you know going in. If you’re one of those people that wants to knock yourself over the head for getting one question on an exam wrong, you should probably prepare yourself for what you’ll experience if you get a list of amendments a page or more long.
Alternatively, if you are the type of person that’s just glad you passed, no matter how well you did, then you’ll probably be happy no matter how many amendments you got.
Also, if you spent the last six months of your Phd trying to figure out how you could justifiably quit, getting lots of amendments may feel like the worse thing ever, because it means you have to do MORE of your PhD, when you were so glad to be done with it at submission.
Whatever type of person you are, you should prepare yourself for what comes after. The viva is scary and stressful and wonderful, all at the same time, and how you react to it is important to understand going in, because it will make you more confident dealing with whatever happens in that room.
But equally, considering how you will feel if you pass magna cum laude, or if you end up with 12 months of amendments and a complete rethink of your thesis, will at least prepare you for the initial ten million thoughts that go through your head the moment your viva ends. And if you can understand how you will react to whatever the situation is, you’ll be more prepared for it.
I tried to be. I knew I was going to feel bad unless I walked out with no amendments, and since the chances of that happening were in the realm of winning the lotto (I assume), I knew I was going to be very conflicted when my viva ended. I didn’t really understand how conflicted I would be. The truth of the matter is that I had dozens of people congratulating me and the only thing I could think about was ‘I have to do another 6 months of this? Why didn’t I quit last year when I had the chance?’
I sipped champagne, went out for drinks, and spent three hours on a train staring into space, and by the time I went to bed that night all I wanted to do was cry. Cry because I’d just done the hardest thing I’d ever done in life…and it wasn’t over yet.
It’s a severe reaction. Most people are just happy to be done the really hard part of it. But, for me, doing amendments to my own work that were someone else’s idea of ‘correct’, was a lesson in sheer bloody determination. And the thought of graduating was the only thing that sustained me for the next 6 months. No, the amendments weren’t awful (most were really easy, and a few were really…well, anyways), but they were still things that had to be done, and they affected the whole thesis, so wording had to be changed, etc. That’s just as much work as editing your draft before submission is (maybe even more, depending on how good your draft was). I felt justified in my reaction, but I also felt horribly disappointed in myself that I wasn’t happier. That I couldn’t seem to get it through my head that I had a PhD. Because as far as I was concerned…I didn’t have a PhD. Not yet. And if I didn’t do the amendments in a much better way than I had – apparently – written my thesis, I would never have a PhD and 3.5 years would have been nothing but a waste of time.
So understand how you’ll react. Try to plan for it. For every eventuality. If you know you’ll react badly to amendments, decide how you’d rather spend your evening. If you know you’ll want to celebrate no matter the outcome, then plan a party. Have something that evening after the viva that you will enjoy, however the viva itself goes. And don’t feel you have to celebrate. If you don’t think you want to celebrate not-quite-but-almost-getting your PhD, then don’t. Even if others want you to.
It’s your day. You do whatever you need to to get through it. And survive tomorrow. Whether tomorrow is ‘I have a PHDdddddddd’ or ‘oh god, this list of amendments if four pages long’.
