<p>^The “extended essay” would be used as your essay for common application. That was my understanding. But now that I read your post, I guess you are saying the “extended essay” is required on top of the common app essay. But either way, the “choose your own topic” essay can be recycled somewhere, if not in common application and you don’t have to answer the “quirky prompt”.</p>
<p>^^Just to clear up misconceptions, the extended essay and common app essay are two separate and required elements. The extended essay is really the meat of the supplement, people easily can get rejected on the basis of it so I’d take it more seriously than some recycled version of, say, your Columbia essay (which they’d probably recognize anyways).</p>
<p>I am in shock no one has mentioned Duke. Optional essay for the trinity school (the one you will go to if you arent an engineer). I didn;t bother doing it and got a likely letter</p>
<p>If I recall when my older son applied there last year, there was at least one essay on “going green” and what he had done to be environmentally conscious. I don’t know if they have any supplementals this year.</p>
