Arts Supplement Deadline - Jan 2 or 3? Help!

<p>I submitted my common app and supplements (including online arts supplement) online yesterday (Dec 30). But I just sent my Pomona arts supplement (which they said they preferred) by mail today. It will arrive on Jan 3, instead of the posted deadline of Jan 2 (which is a holiday). </p>

<p>Does anyone know if this will affect my application (i.e., will they look at my mailed supplement?).</p>

<p>Also, my teacher mailed in my recc instead of online, but on the common app website it says my school forms section hasn't been completed. Is this ok? How will I know if they received her letter? </p>

<p>Thanks.</p>

<p>So glad this is all over... almost (except in my nightmares).</p>
