<p>Ok so I've noticed that a "priority deadline", or a "Post-mark" date for Penn-State is November 30th. I need to quickly know the answer to whether or not we can actually mail it out on the 30th. The admissions office told me that was the "Post-mark" date, so will it be fine if I mail it out on the 30th during the afternoon?</p>
<p>The same goes for other colleges who have a priority deadline", or a "Post-mark" date for December 1st, can I do it on that very day, or do I HAVE to do it the day before?</p>
<p>Thanks a lot, and quick responses would be appreciated so I could figure this out.</p>
