Possible options with a 680 and 3.0?

I have 3.0 GPA with an Econ degree and business admin minor from a top 40 undergrad school and a 680 GMAT (40v,44q) and a 6.0 on AWA section (91%) I'm graduating in three years this May and although I don't have post-grad work exp I have been working full-time on a commission basis for an IT firm for 2 years and 3 months as a financial adviser/supervisor and recently left to apply for grad school and also extra summer work experience. I also have a misdemeanor DUI on my record about a year and a half ago that I've declared in every application. I also have extracurricular leadership experience and I volunteer at two community service organizations and fluency in two other languages (aside from English). I've applied to 10 schools already, Yale, Vandy, UC Berkeley, UC Irvine, U Maryland, U Texas Austin, Duke, USC, Northwestern, and Georgetown. I sent the applications in before the Round 2/3 deadlines for each school. Should I apply to more schools for the next round or do I have a legit chance of getting into any of these? Thank you
