<p>your supplement was submitted before the deadline, but the application was submitted after? Does it count as late? Which schools are super strict about that?</p>
<p>It probably depends on the school. I sent my application to Beloit on time, and although I submitted my supplement on the day it was due, common app listed it as being sent the day after. I called them to make sure this was ok, and they said they are pretty lenient when it comes to that. I would suggest calling the school.</p>
