It may sound like a chore, and it will certainly take a substantial amount of work. But it's also a unique opportunity that can make a difference at decision time. Admissions committees put the most weight on your high school grades and your test scores . However, selective colleges receive applications from many worthy students with similar scores and grades—too many to admit. So they use your essay, along with your letters of recommendation and extracurricular activities , to find out what sets you apart from the other talented candidates.
Identity : This is the pivot of the prompt. However you address this prompt, you are being asked about your identity. You are asked to address the fundamental nature of how you see yourself as a person. Who are you? What are you? What makes you, well, you? Admissions officers want to be able to say, “hey, I understand who this kid is and where he came from, because the kid understands this about himself and is able to communicate it in a clear, compelling fashion.” So, this essay must address your identity, however you define it.
