<p>I know this has been asked before...but I'm kinda freaking out. I haven't recieved my letter from CMU yet and have lost my ID (I can't check my decision online). I tried calling and emailing CMU but its sunday so I don't think I'm going to be getting a reply anytime soon...what should I do?</p>
<p>They will not simply give you your ID. They will mail it to you so you might as well just wait for the official letter :)</p>
<p>Of course it is beneficial to have your ID so I would request it anyways and have 'em mail it to you. Good luck!</p>
