URM at Columbia GS

I initially attended a four year university in 2001 and eventually dropped out due to subpar performance (2.3)/ financial reasons. I was enrolled in another four year university from 2007-2010 and withdrew with a cumulative GPA of 3.73. Since the spring of 2010, I’ve been working in the tech industry and am now a principal analyst at a INC 500 company.

Recently, I’ve been thinking about finishing my degree and this program seems like the perfect fit (I’m particularly intrigued by the CS major w/ a concentration in Statistics). However, before I really immerse myself in the application process, I would like to know if I have a legitimate shot. Also, I haven’t taken the ACT since 2000, does anyone know what GS’ 25th and 75th percentile scores are? Any feedback would be greatly appreciated.
