Lily 714:
I know you are looking to get your hopes up from hearing past stories. I am in a similar boat. I have a 3.97 in math, which, yes, includes real analysis (A). My GRE Q score? 740. I share your frustration, and I too would be happy to hear of people who succeeded despite this.
My sad conclusion is that it just doesn't happen. People don't break programs with lower scores because the adcom just throws out the application. My solution might be of interest to you. I am now pursuing a masters in statistics. If you like economics, you like quantitative thinking and you like to answer questions about the world around you. What better discipline than statistics? I'm actually siked that I have decided to go this route. This will surely help boost your credentials and give you a change to take, say, grad level econometrics. Moreover, at UMICH, they let you take classes in pure economics -- not just metrics -- towards your statistics masters as an elective. This would really boost your credentials
So don't give up. You could also get a masters in math. And all the while keep practicing. I know you don't need to study pythagorean theorem or basic combinatorics. The way I have been told to get my score up is just practice, practice practice. Get really comfortable so that, on test day, you are ready for 3 hours of 8th grade brainteasers.
Good luck!
