Master's Thesis unexpectedly going south but admitted into PhD program next fall I was recently admitted into a PhD program, and am currently a MSc Student. Both me and my advisor expected me to graduate this spring, which would mark the 4th semester. Because of that, I applied to PhD programs, and got into a good one. But now I think I might need a bit longer to complete the Thesis portion of it; I could switch to MA which is course based and head on to PhD 1) I am not sure if they will still accept me if I do not have an MSc (the strength of my application was the skills I learned during my thesis) and 2) I want to finish my thesis, because well, I want to publish the results and am interested in it. 

What are my options? Many programs do not allow deference, and getting into a PhD program is so hard to begin with.

Thank you for your time.
I don't know the details of your situation, but the conventional advice would probably be:


Pound out a thesis that's good enough for your advisor to let you graduate. It doesn't need to be outstanding or publishable, or include every idea you've considered. It just has to get you the masters.
Start your PhD program on time.
If the project still interests you, continue working on it in your spare time. Stay in contact with your masters advisor. When it's far enough along to publish, do so (perhaps with your masters advisor as a co-author).
