Delayed doctorhood...

IT is looking more and more like I won't be graduating in August and will have to wait around for a December graduation. I got my dissertation draft back with about 100 significant changes I need to make. I don't think I can get them done before the 7/7 deadline. :( Especially since the document would have to be done by 6/30 to get out to reviewers. I am feeling frustrated with the process...and wondering if a different chair might have been less demanding. :)
