<p>If the enrollment deadline at the schools I have gotten into is May 1st, do I have to notify them whether or not I am attending BY May 1st (by 11:59 P.M. April 30th) or do I have until 11:59 P.M. on May 1st?</p>
<p>You should call the specific schools. Some require postmark no later than May 1st. Others want the information received May 1st.</p>
<p>Most schools just want it postmarked by May 1st.</p>
