Hi Astronautka,
I'm an international candidate too, hoping for a breakthrough somewhere.
GRE Scores can be compensated if you have a strong SOP and good writing sample(s). Of course good LORs too, but that's something which isn't really in my court. I know of someone who got 1100 in GRE but he had a good publications list and a strong statement. He got into a top school with full-funding.
I have low scores in Quant and writing..but don't want to retake the test. Thinking of strengthening the rest of the apps package instead.
Which area are you applying in, if I may ask?
