<p>I believe Carnegie Mellon does yet another different way. They post online that your result has been snail-mailed, and then after a week or two they post the results online (in case it got lost in the mail).</p>
<p>OP, you may get best info from checking on CC in individual school forums for all schools your S applied. On CC, the first whiff of admissions results start a flurry of posts.</p>
<p>And if you want a head’s up, check last year’s results threads for the dates and methods used in the past.</p>
<p>Madbean is obviously a CC sleuth. Great idea.</p>
