questions on next phase of my app?

<p>hello there cc readers,
i haven't yet submitted the supplement portion of my app and had questions regarding the next parts, which i obviously cant see.
1-is there a area for teacher reccomendation letter? for how many? for which teacher?
2- can you upload a new improved essay or is it only a one time deal?
3- upenn says the essays are one page in length, but doesn't specify the margin size, could we change this for more area?</p>

<p>thanks for the help

<ol>
<li>School forms section.</li>
<li>Upload it when your done.</li>
<li>I changed my margins so it would fit. One sentence was on the next page.</li>
</ol>

<p>thanks, appreciate it.</p>
