I am unable to find any information online for this, so I felt that you all might be able to help me. I am applying for the NSF as a first year grad student. I just started my program ~3 weeks ago (quarter system) and I obviously do not have grades yet (haven't even taken midterms). I am wondering what numerical value to enter on the Fastlane application for my graduate school. It only takes numerical values, "N/A" or some variation does not work. I must put a numerical value under GPA for me to add the institution... While I am confident that I will do well in my classes, I don't want to put a "3.7" or "4.0" or some variation in case that changes. I'm sure there is a simply fix that others have used in the past, I just can't seem to figure it out. Good Luck to everyone on this application cycle!!!
