I passed! I think the revisions required for my dissertation are miraculously minor (although it's not 100% clear to me what they are yet). I did it. This crazy beast is 99.9999% done. I should be able to finish the revisions in the next few weeks, and then I'll hold on to my dissertation until I have a job. My committee has endorsed my backup plan of staying on as a TA in the fall if nothing else comes through.
One question that I think my readers can answer for me- when do I officially get to be called Dr.? Now that I've passed my defense? When I get my diploma?
