Thanks, I do think I am worrying a lot, it's just that I'm really anxious about one of the professors who are writing me a reference letter: I asked him when he was in a bad mood and he sort of took some questions I asked him the wrong way. Are you two U.S. permanent residents? If you are, then you aren't considered international students since you are eligible for U.S. gov't grants.I think you're worrying a bit to much. My sister and I are nationals from Nicaragua, but I came to the United States before high school. My sister stayed. She did her undergraduate at a national university, and now is doing a Masters at USC. By no means is any undergraduate university in our home country even close to the reputations of UT, but she managed. As far I can tell, her GPA was around 3.86, GRE subject around 820 and i'm not sure about her general.
I recently realized something that might complicate my application: my school converts percentages to GPA differently from most schools. Here, if your average mark in your course is 85% or above, you get a 4.0 (an A). 80% and above is 3.7 (A-), 77%+ is 3.3 (B+), 74%+ is 3.0 (B), etc. But I think at most schools you need 90% and above to get 4.0, and 85% is only a B. So does that mean that schools will view my 3.25 GPA as a 2.25 GPA (!!!)? Keep in mind that my school marks hard and that the class average in physics is a 2.46 GPA (~ 69% in percentage based on average marks in a course)
