<p>This is probably trivial - people send one main CommonApp essay to many schools all the time. But what if I use the SAME essay for different colleges' supplements - would they know?</p>
<p>Do they even share and compare essays?</p>
<p>No, they won't know. They don't share and compare essays. And it doesn't matter anyway. If the essay answers the prompt, and it is not plagiarized (they do sometimes check for that), then it's fine.</p>
<p>Cool, thanks.</p>
<p>congrats on your 3600th post btw hahaha</p>
