I really like the personal challenge essay that I wrote. It talks about coping skills, a major pastime of mine and what I learned from it, and I think it overall paints me in a positive light and highlights parts of me that don't didn't have a place in the rest of my app. For schools that leave space for a "add something" or "is there anything else that you would like us to know about you" essay, would it be appropriate to say something like "I think that this example of how I approached a difficult personal situation will provide you with insight into my character that would otherwise be missed" and then add my personal challenge essay? Obviously, I expect that these schools would be familiar with the idea of this essay despite not asking for it, but would it be weird to include it like that?
