GMAT score 680 - need advice for application

Hi,

My GMAT score is 680 (84 percentile). Split

Quant - 50 - 88 percentile
Verbal - 31 - 61 percentile
IR - 5 - 52 percentile

My verbal score is rather lower than my expectation (74-78). I know schools does not have any hard stop for scores as long as other criteria is superior. But i have a question is my verbal score too low that my application can be rejected right away?

Brief about my background -
Education - PhD (Chemistry)
Undergrad GPA - 3.0
Work experience 3 years (USA, after PhD) + 2 years (India, after undergrad)

Schools targeted - Sloan, Duke, UNC, Emory, Georgia tech, University of Virginia, UT-Austin.
Can someone please tell what can be my chances for these schools.

Thanks
Swapnil
