Rescinding an ED admission?

<p>Just out of curiosity, does this ever happen? I’m assuming it is much less common to rescind an ED admission than an RD one, because the kids who were admitted had to withdraw their other applications and would thus be stuck without any school at all to attend. However, I also know that they check mid-year reports and if the grades drop, you can be in trouble…but how common is this in reality?</p>
