Quote From phdproject:
UK. I am on 3.5 years funding program, by the time I would submit my progression report I would be left with 17 months to complete my PhD which is my main concern. The committee might not be convinced that I could get results in 17 months.
There is no point beating around the bush - yes there is a risk they may not be convinced you will complete but consider a coiuple of things.
1) Your supervisor and your university will not want to fail you. It reflects terribly on them.
2) Most people don't have much published at your stage.
3) The overwhelming majority of those who make it to submission will eventually get their PhD. Very few fail.
4) The deadline for submission is not 3.5 years. You will be allowed to continue beyond that date. Most people take 4 to 5 years in the UK.
You are probably in better shape than you think.
