The selection process is tough. Your admissions interviewers are doing their best to find future alumni in the applicant pool. This question asks you to explain why they should choose you. Go beyond what all the other applicants will probably say in response to this question. They are all talented candidates, have stellar grades, a drive, and the potential to be alumni.

You can find this on a brochure on their website: "Many factors are considered in selecting students for admission, including the applicant's academic performance, motivation, extracurricular activities and interests, related and unrelated work experience, personal achievements, essays, and letters of evaluation. When evaluating academic performance, the applicant's grade point average, performance in prerequisite courses, number of college credits completed per semester credit load, degree status, and results of the Optometry Admissions Test (OAT) are carefully considered." These are the sorts of things that can set you apart.
