Hi there ,
1/I have already submitted my PhD thesis, and when I did rereading I found that
1/ I forget to cite references ( 3 or 4 cite references)
Basically after writing some sentences I write this -> (cite something later ) at end of each sentence to cite a reference about that to remind me adding the references later, so I forget to add those references or even remove the (cite something later ) which will be easy to noticed , iam worried the examiners will see that.. :(. .
2-Also in the experimental chemicals part I added by mistake some chemical names that I didnot use it and I’m worried about that too .
3-Also two or three figures number mistakes ) ..

Would that be considered as minor correction or major correction?

These would be minors. Just note them all down in a list so that if the examiners mention them, you will be able to say something like yes, I am aware of that and will get it fixed. My friend found 37 errors in hers. I don't know how many errors I will notice in mine, as I haven't dared look at it since submitting!

Good luck with everything!

I submitted at the beginning of the year and like you, found minor errors after. I just took a sheet into my Viva with me and at the end when they spoke of errors I said "yes I am aware of erros X, Y Z, I have already addressed them but had already submitted before I noticed them". The examiners were fine with that... I passed with just a few minor corrections so it cant have been too much of a problem. Good luck with your Viva . Max
