Hi! Your GMAT score is OK - of course, getting a little higher would have put you in a more comfortable spot, but your quant score is very strong and that really matters in the admission process. In fact, most schools are focused on your quant much more than your verbal. I am not sure why you think the higher quant would hurt you - in fact, it is sure to help your chances of getting into a competitive school.
As I reviewed your profile, it looks as though you have some strong professional experiences to talk about in your applications. I would encourage you to really find ways to highlight your accomplishments, not responsibilities, at work, and look for stories within your professional life to showcase your strengths. You also seem to have a strong roster of extra-curricular activities. With those, too, look for ways to present your leadership through your outside activities. I also think your journey from Korea to the US as a teen could make for a powerful story in your applications. Really think about how that life experience has shaped you as a person. What did you learn from it? What has it effected in your life?
As for the schools on your list, I think you shouldn't write off Wharton or Columbia. Yes, your GMAT is on the lower end of both schools' ranges but that doesn't mean don't apply. Just make sure that you have other schools, too, on your list that you would be happy attending.
Best of luck,
Rachel Beck
