supplement??

Hey guys do you know if Penn looks for an essay that more prefers a narrative about life or an essay of like the programs and what you want to do with them? I know commonapp has to be a narrative, but i’m wondering how to structure my supplement?
(sorry if this question’s wording doesn’t make sense, i’m running on 3 hours sleep.)
