Is ED2 really worth it?

<p>How much of an advantage is applying ED2? I heard it basically has no effect...</p>

<p>Two schools I'm applying to are Emory and University of Rochester. I'm not completely set on either one, so I shouldn't bind myself, correct?</p>

<p>If you are borderline, ED can really help at these schools. Just make sure you can afford them.</p>
