<p>Is there any way, aside from e-mailing Yale's application materials e-mail address, to determine if your supplemental materials have been received by Yale?</p>
<p>As supplemental materials are not part of the application requirements, you just have to assume they arrived and are in your file. That true for Yale and most other colleges.</p>
<p>You get a confirmation email if it’s a music supplement.</p>
<p>Thanks guys! I submitted a supplemental rec via mail, so I was wondering how I would be able to tell.</p>
<p>But thanks again :)</p>
