Ask Stacy Blackman

Hey guys,
I'm interested in honing a list of schools to visit this spring in advance of applying in the fall. I'd really appreciate some feedback as to whether or not I'm a viable candidate. Here is my background:

-University of Florida Graduate (top 50 college in US News).
Major: Business Administration - Marketing. GPA: 3.5

-Work Experience:
1 year in rotational management development program at publicly traded company
2 years at middle market investment bank as an IB analyst (top decile-ranking of analysts both years)
2 years (at matriculation) at middle market venture capital firm

-GMAT: 700 Total; (59% - Q; 99%-V); 6.0 AWA

-Extra Cur: President of 100 man fraternity in undergrad; founded philanthropy benefiting MDA in undergrad; 3 years volunteering in at-risk schools tutoring middle schoolers about financial topics while working; guest lecturer at University of South Florida on VC/PE to graduate level class (3 lectures) while working

I'm concerned that my low quant score on the GMAT is going to hold me back. Will my quant-heavy background in IB and VC make up for this? The score was a fluke, but I no longer have time to study for and re-take the test.

Schools I am most interested in targeting:
-Northwestern
-Columbia (Will ED help?)
-Duke
-Yale

I appreciate the help. If I can approach my selection process intelligently now, I intend to reach out to a consultant in the fall to help refine my personal message. The help is greatly appreciated.
