I received the award in Life Sciences - Animal Behavior, although my overall scores were lower this year than last year, when I got an HM.
This year, I got VG/VG, VG/E, and E/E. Last year I had two Excellents for my Intellectual Merit; however I had two VGs and one G for my Broader Impacts. It seems that bumping up the broader impacts really helped. One reviewer literally cppied and pasted my broader impacts paragraph into the BE section for his/her review, haha.
To be honest, it seems like the reason I was awarded a GRFP this year was due to the overall package, moreso than this particular proposal. The reviewers that gave me VGs mentioned some issues they had with the proposal itself, but said that based on the rest of the application and my previous work/publications, they felt that I had potential.
Moral(s) of the story: put effort into your personal statement and research experience as well as the proposal, and it's always a crapshoot.
