Will this help my chances?

<p>So I am a junior in highschool now, have about a 3.8 gpa, (waiting to take SATs soon), and have very good ECs. My stepsister (who I live with) just got her acceptance to Columbia for graduate school. I am just wondering if I put on my application that she’s attending graduate school at Columbia, will that give me a slight “hook” and possibly increase my chances of acceptance? </p>
