I usually don't procrastinate, but I've found myself avoiding my two December 1 deadlines (UCLA and Maryland) like the plague. Yesterday, I FINALLY finalized the list of schools I'm applying to and sent my transcripts/GRE scores. I graduated in May and took the GRE in August, so I could have sent these a while ago. My advisor assures me that even if they aren't in until after the deadline, the schools will still consider my application. One of my letter writers was not happy that I only gave her a finalized list of my schools yesterday, even though she wrote a letter for my NSF GRFP application.
Still haven't finalized my personal statement though, but I have my essay from my NSF that I'm just going to shorten. Fingers crossed!
