<p>I know that on their site they said that they don't read any additional material..... so if I sent in an essay about a robot I built that I think really showcases my passion for engineering, will they just chuck it without even reading it?</p>
<p>Why would you risk annoying anyone dealing with your file? Their rules are quite explicit and you want to blatantly disregard it --- all this for the slimmest of potential boosts by the content of your essay --- I highly advise against it. But it's your file...</p>
<p>well..... I already did it at the same time I submitted my app.... and THEN read the website (I know..... stupid me) and went OH NO! I hope they don't get too mad....</p>
