A quick note from conversations I have had with students. The hand-in date is May 14th. For things that are being mailed in this means you must attempt to have them post marked May 14th . You do not have to send them to arrive on May 14th because some people are on the other side of the world and would have to send things a week before or something. So this way everyone has the same cut off date. However you do need to email you work to arrive by May 14th.
