<p>spideygirl: SCEA is restrictive in that you can't apply EA elsewhere (with some exceptions of rolling admissions schools). However, if accepted, it's non-binding on you (unlike ED which is binding on you)</p>
<p>sunriseap: the reason most EA/ED apps are deferred is that they are still viable candidates (due to the generally higher quality and number of "serious" apps versus the whimisical "I wonder if yale would take me" app). If an EA/ED app is considered non-viable (read: no chance) then it WILL be rejected. I highly doubt there are goals for "defers" and "rejects" from the early apps. There may be caps on the "admits" I suspect.</p>
