You can certainly request another second supervisor, perhaps approach one of the other academics you get along with(?).

At this point the main thing you need to be sure of is that your supervisor is happy with your progress. I suggest a meeting and asking him directly.

I personally would just keep going, another year is nothing and I wouldn't want to lose 2 years work. I knew a guy who absolutely hated his PhD (and his supervisor) and kept on through it for 3 years, I certainly wouldn't advise this but in the end he passed and is now doing research in the field of his choice.

Many thanks! Yes, of course I did the work but the support from my supervisors was amazing, they were there every step of the way.

Well, that's it I got the best possible result and my PhD is finished!!!

I spent a long time lurking on these forums before my PhD viva, continuously reading the horror stories which range from major revisions to R&R to MPhil to fail.

One thing became immediately apparent the choice of supervisor is KEY. I was very, very lucky in that my supervisor was readily available, offered amazing advice (both academic and personal) and read my work thoroughly. There is no way she would have even let me submit my thesis if she thought it would not have achieved a pass.

Another consideration is that my secondary supervisor also read my work. So in effect it had been peer reviewed by 2 people before entering into my thesis.

Looking at the horror stories probably wasn't so helpful but in some ways it did help prepare me for the worst. So I thought I would contribute back and say that to anyone thinking about a PhD (or who has just started and has poor supervision) really choose your supervisor carefully!

Any other questions welcome!
