My undergraduate work---Government/Humanities BA with 3.7 GPA, magna cum laude Graduate work---MA Philosophy (anticipated May 2010 graduation) with TAship; GRE verbal 74th percentile, quantitative 79th percentile Current volunteer position as Volunteer Coordinator for community health center; will head fundraising, political activism, and grant-writing efforts Other various honors, etc. Where should I apply? What are my chances? Thanks!
