Need Help W/ LOCI for Columbia

Hi all, I'm at a T20 and finished my first year with a 3.91 in hard courses. I got waitlisted my Columbia and really want to attend. I am writing my LOCI and talking about the Core Curriculum and other things that Columbia offers such as the Columbia Mentoring Initiative. Does anyone have any tips on what to include or what they take away from their experience at Columbia (if attending there) that I should include? Thanks.
