<p>I’m a RD. I chose the “send supplementary materials” box in my application for Columbia U and sent my slides through mail to the admission office. However, I have no idea if it really got there or not because they don’t show the status for supp materials in the application tracking on their website, only:

<p>Since they said they might not look at the supp materials, I’m not hoping for any real boost. I am wondering if they only start checking my application AFTER they received my supp? Should I send an email to ask? </p>
<p>did you send in the slides with certified mail? i think you should’ve. that way, they’ll send you a little green note back with a signature, showing that they received it.</p>
<p>No I didn’t, I wish I had :(. I’m an international student so the mail takes around 2 weeks to get to the US, and I already had to resend one of my app materials (to another school though) because the mail got lost.</p>
