Dear top10hopeful,
I think you are wasting energy worrying about your quantitative score. It is not that low and your total score is competitive. Likewise, the grades in those two classes are not great, but your overall GPA is high and you have other aspects to your background demonstrating your quant/analytical skills. Quit worrying and start writing some awesome essays! These schools will be interested in your profile, especially your work experience and leadership potential.
Best of luck,
Lisa
