<p>Relax. Most schools have a grace period after the deadline (ranging from a couple minutes to a couple of hours, depends on the school). I submitted my app to Stanford 3 minutes late (Stanford is notorious for their strict deadlines), I emailed the admissions office a couple minutes later and they said it was fine. I mean, a school is really not going to toss your app out because it was one minute late. Relaxxxxxxxxxx.</p>
