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.
