Dear Dunni,
Thank you very much for your encouragement.
i keep on finding things in my thesis. I have around 3 or 4 pages that are in the exact wording like journals or websites and also some result headings that are in the same wording like my internal`s PhD Student, also there is a table were I have messed up the percentages.
i am so scared and I dont know what to do.

I am really worried, no TERRIFIED, about my viva!!!!!!!!!!!!!!

I just found bits in my thesis that I had gathered from a review and had the intension of writing in my own words, but forgot to do so, and have included them in my Thesis in the exact wording like the review!!!
Also, it seems that I have methodology similar to the thesis of a phd student who was supervised by my internal examiner.

Any advice?

:-(
