How to report GPA, if minimum letter grade credits not reached?
It seems the National Defense Science and Engineering Graduate (NDSEG) Fellowship states:


  What GPA do I enter for my school if I just started attending? You can
  enter 0.0 as your GPA – reviewers will understand that you have not
  yet received a GPA for that school and will not view it negatively.

Will follow-up if I receive any formal statement from the UCSC Office of the Registrar.
