I am one month into my third year!
It's been so fast for me, too...
I never thought that by my third year I would have been writing (I have already 2 chapters ready and a third one as a schedule) as I am working full-time, I am doing my PhD part-time AND I am living in another country (and have another first language)....
Typically, I am not in my final year yet, but I feel like I am! As a matter of fact, if I wanted, I guess I could finish by June, but I don't want to pressure myself do muc (mind you I am not very young, I am 32, and I also want to do other things in my life than working and writing all day)!!!!!!!!!
