<p>I’ve been filling out the app myself today, and I was a bit confused as well. BUT I did find the supplement! Here it is: </p>
<p>[Binghamton</a> University - Undergraduate Admissions - Freshman Applicant Criteria and Application](<a href=“http://www2.binghamton.edu/admissions/apply/freshman/stars.html]Binghamton”>http://www2.binghamton.edu/admissions/apply/freshman/stars.html)</p>
<p>You need to make an account on STARS in order to fill out your self-reported academic record. I’m positive thats the only required supplement.</p>
