<p>IS Chicgo single choice early action or just plain old early action? In other words, can I apply ED to princeton and EA to Chicago?</p>
<p>Yes you can, Chicago's EA policy is totally open.</p>
<p>But what is Princeton's policy?</p>
<p>Princeton, being ED, only stipulates that if accepted ED, you must attend, and makes no restrictions against applying to an open EA school like Chicago. So, I am positive that you can apply to both under their respective early policies (if you want to prepare to apps, that is).</p>
<p>You can apply EA to Chicago and ED to Princeton. In fact you can also apply EA to Georgetown, UNC, BC and Notre Dame at the same time.</p>
