<p>I applied to 7 schools - no EA or ED - and I heard from two in November, one in January, one in February, two in the third week of March, and the last one on April 2nd. No heart attacks. I was relaxed because of the November ones - I knew I had somewhere to go.</p>
<p>No, results do not all come out at the same time on the same day. Some decisions will be posted online, others you have to wait for the snailmail. Some start reporting decisions around March 25th (or earlier), others wait until precisely April 1st. Check individual college forums for last year's threads.</p>
<p>I'm pretty sure all of the Ivies release decisions at the same time (an agreement between them, seems reasonable to me). Last year there were threads with the people posting the order they were going to check them!</p>
