<p>So now that we've been accepted under early decision, we need withdraw our applications to other schools.</p>
<p>My question is whether I even have to withdraw if I've only sent in teacher recs, a transcript, and test scores; but NOT the formal application.</p>
<p>I doubt it; they can't accept you if you haven't sent in your formal application, so there's no need to withdraw, right?</p>
<p>it's still polite to let those schools know that you were accepted ED elsewhere.</p>
<p>Don't bother. The other schools aren't sitting around waiting for your app -- you're just one of 15,000 applications. They're not going to accept you if you didn't send in the formal application, so you don't have much to worry about.</p>
