How badly do you have to do to have your Early Decision Admission rescinded?

<p>Specifically for Columbia University...how bad do you have to do? I mean will a drop from a 95 to a 85 avg look bad enough to screw yourself over?</p>

<p>That wont hurt you, IF you get accepted ED, but you are betting the farm on that. If you get deferred, or have to apply to other schools, than that drop might lessen your options.</p>
