UIUC/Purdue recommendations? UNC app?

<p>I know there are Teacher recommendations for UIUC or Purdue, but what about counselor recommendations?</p>

<p>Also, for my UNC app, the teacher recommendation email sends AFTER you submit your entire application. If i wanted to change something, say an essay, is it possible? or no? I know this is a pretty dumb question...</p>

<p>buuuuuuuuump!</p>
