<p>OK, this is something that I discovered and may be a problem.</p>
<p>When you make copies of an application online, you are only allowed to put a school on one copy. Therefore, if you had Yale on "application 1" and made a copy, you couldn't add it to the "application 2" list before removing it from "application 1". On the good side, even removing it won't erase your supplement work.</p>
