<p>If you apply ED, one of three things will happen.</p>
<p>ACCEPTED: self explanatory - you have to attend provided they give you enough financial aid and they decide if they have or not</p>
<p>DENIED: you are out and can not apply again for a year</p>
<p>DEFERRED: they will automatically reconsider you during RD - the truth of the matter is that it is unlikely you will be later be accepted since the competition only gets tougher</p>
