<p>I heard you can change the content even after the submission, so I was wondering if you can change the essay after you submit the application. Since the teacher recommendation email gets sent out after you submit your app, I was wondering if I can submit my application now so she will recieve it and work more on my essays and slip those in after my submission.</p>
<p>You should ask this on the UNC admissions blog. As I understand it, your entire application must be in by the deadline - meaning the student portion - other items can come in after the deadline.</p>
