University: Just outside top-50 business school
Academics: Quantitative Economics, 3.7 GPA, 3.9 in-major, 4.0 in math
GMAT: 740(97%), 48Q(78%) 44V(97%)
Work: Corporate finance, fortune 100 bulge bracket; plan on working for 3 years before applying
Ethnicity: White hispanic
Extracurriculars: Avid guitarist, but this is about it. Charity is important to me, and I need to find a good community service program.
What are my odds at the top 7, and how can I improve my profile, particularly through extracurriculars? I hope that my math background helps to ease concerns about my GMAT split. Any advice is greatly appreciated.
