Thanks all for the advice and encouragement. I'm a "non-traditional" student in that I went into industry a few years before returning to grad school. It's frustrating to be haunted by things that happened a decade ago but hopefully that growth will come through in my essay and grad work. Gotta play to win right? Best of luck to everyone!
Was wondering if anyone had any insight as to the weight of graduate GPA vs. undergraduate GPA for the NSF. I've heard from a faculty member who's been on the review board that without a 3.2+ ugrad gpa it's incredibly unlikely you'll win. Has anyone heard of a 3.0 (or less) ugrad GPA being viewed more favorably with a higher graduate GPA?
