I got 710 (Q43 %70, V45 98%) a few weeks ago. I just as easily could have come away with a 670, so I'm grateful for what I got, even if it's lopsided.
I'm also hoping that my A's in quantitative classes resolve any concerns the adcom will have. I had to take four classes that required Eng. Calc II as a prerequisite. I have a friend at <ultra> with a 710 (Q%68, V%99) who was rejected last year. His major was non-quantitative. He took a few classes at a cc and reapplied... got in. From what I've read: retake the GMAT or have some quant classes on your transcript.
I talked to a student ambassador from Michigan (great outreach program, if you haven't tried it) who told me that the school wants to know that you can handle the quantitative nature of b-school, but once convinced, the overall number is the only thing that matters. Will you help or hurt their avg? This reinforces my thought that A's in quant classes will offset the lopsided score.
BTW, it was sort of therapeutic for me to see all of you here with similarly lopsided scores.
Good luck.
