<p>The Princeton supplement requires 2 essays in addition to the Common App personal statement. Did you use your "most meaninful activity" essay (Common App, page 4) as one of the 2 extra? Or did you write 2 entirely new essays?</p>
<p>If you use the common-app, then they already have the "most meaningful activity" essay, so don't use it again, but write 2 new essays.</p>
<p>If you use Princeton's app, if doesn't ask for that, so you could use it as one of your essays. However, the downside is one less essay for them to read (although it is only 150 words or so, I believe).</p>
<p>I used the Yale one, again, too. (I did the Princeton App.) What I did: wrote the Yale Supp essay, summarized it for the Common App Short Answer, expanded on it for the other Common App colleges' short answer since this time I did it on the fillable pdf and had more space, and then lengthened the introduction for the princeton app.</p>
<p>for the most meaningful activity, there's a thread on the yale board.</p>
<p>that is the problem with using the common application. i really doubt that they want two essays on the same topic. this confusion is prevented by using their school-specific application. if u wrote about a meaningful activity for the common application i think it is common sense that u would choose 2 different topics for ur 2 princeton short 250 word essays</p>
