Hallo ..actually I totally feel you..I have done my viva in March 2019, after a couple of rehearsals with my two supervisors, and I was shocked when they told me the data is not enough!!!! and I need to go back and do it..but this is all fine ..what is killing me now is second supervisor retired, and my initial supervisor I am his first student, and it seems whatever i am submitting is not good enough. I have shown my writing to three different professors who supervised a lot of students and they all said my writing is really good and up to the PhD standard. when i ever i ask my supervisor for guidance or clarification, he answered saying i am here to advise not to guide ..long story short, i am in process of transferring my paper if someone can assist me on how is the best way to do that, do i search for university get initial approval and then transfer or how does this work. thank you
