Feeling a little overwhelmed and dismayed here.  With a 600 GMAT score, what are my chances at top 20 or 30 schools (UNC, UT-Austin).  The rest of my profile is, I believe, really strong and unique.   
I'm a 28 year old female, currently working for a fashion magazine, was a fine art major, undergrad GPA 3.9, strong ec's (volunteer work, marathon running, etc).  Marketing is my career goal, and I'm not overly concerned about writing compelling essays, creativity and "having a way with words" is just something I've always been good at.   My huge negative check mark is that pesky GMAT.
Words of advice?  Give it a shot?  Retake the test (not sure if I have time to study enough to increase my score), and... just for kicks... what would my chances be at Duke or Ross with a 600?
Thank you.
