<p>Faelivrin: If commonapp.org allowed you to submit it and didn’t bounce you with a “deadline has passed” message, you’re probably fine. I really wouldn’t worry, although it wouldn’t hurt to call U.Penn tomorrow (or just watch to see if your application is downloaded, in which case you’re almost certainly golden).</p>
<p>I hope you don’t have plans for tomorrow morning; sounds like you need to sleep in.</p>
