<p>I know the main difference between EA and ED is that ED is binding, but I have heard that EA is more selective than Regular Decision. Is there any truth to this?</p>
<p>Possibly. EA may be more selective than RD because colleges theoretically don't admit borderline applicants EA. Instead, those people get deferred into RD. But overall, EA probably can't hurt you... I doubt someone who was rejected EA would have gotten in RD.</p>
