<p>Which one did everyone use? And does it matter if you don't use the Duke App? Because I'd rather just use the Common App since I'm already going to have to fill it out for other schools...</p>
<p>don't worry! common app is perfectly fine! you won't automatically be put in the reject pile because of it and there's no preference against it. I'd bet a majority of applicants end up using it; I used it last year and I was accepted.</p>
