I applied as a 1st year Ph.D. student. My reviews were:
IM/BI:
VG/VG
E/Fair
I did not receive a third reviewer. My negative comments were:
First reviewer, IM (VG): Discuss more regarding experimental (or otherwise) validation of theoretical and computational results.
First reviewer, BI (VG): Discuss more regarding the broader impact of the research topic itself.
Second reviewer, IM (E): No negative comments.
Second reviewer, BI (Fair): Discussion of broader impacts was absent in previous research document. Also, insufficient discussion of broader impacts in research proposal.
I feel very disappointed because I feel I had an excellent research proposal. Having not applied last year, this was my first experience trying to gauge where and how to incorporate BI. The first and second reviewers obviously differed greatly in their opinions of my BI discussion. I just wish I could've gotten the third reviewer.
I will definitely try again this coming Fall, but it will be more competitive.
