GMtest, I think I'm going to have the same problem soon. I have also been recommended by my department to the grad school, but my GPA is a little low. I was already asked to support my application by a professor in my department b/c of my GPA and he replied and said he recommended me for admission. I also just met with another professor from my department today and it seemed to go well. Did you experience any professors in your department asking you to defend your GPA? My status still says "The Graduate School will be reviewing your file."
I'm so nervous!
