SLCs and sororities at Duke

D22 loves Duke on paper, pics and website, but recently discovered the 42 pct sorority participation rate. She is very studious, hard working, not into parties or getting made up, and fairly reserved. She enjoys company of small group of friends, boyfriend, watching movies/series, going for a walk in the park, baking, etc. And the elitism, competitiveness and selectivity of sororities is not something she enjoys or wants in her college. Is Duke a good fit for her?
