<p>Which is better to use? My commonapp essay is really good, but I don't know if it will fit with the essay choices on the Pton application. I need to know soon since I have to give my teacher rec forms.</p>
<p>I believe that if you have an essay you really like, you should send it with the Common Application if necessary. That being said, though all colleges scream otherwise, if they are to prefer one application over the other, they will go for their proprietary one. Princeton presents an interesting dilemma because, unlike Yale or Harvard, it has a proprietary application to create that "what if?</p>
<p>If your common app essay is good use it.
Spend some time being creative for the Princeton's supplemental essays as that will be a deciding factor.</p>
<p>From everything I have heard since last year Princeton will not penalize you for using the common app over their own app.</p>
