Common APP question

<p>Sorry if this was posted already but i honestly did look through other threads and did not find this.</p>

<p>On the common app site, it tells you the essays ( i think theres 6 ) that you have to write for, and how they are the same as last years.</p>

<p>Do we have to write ALL of those essays? or just pick from one, and then when applying to a college on the list that uses the common app, we have to submit that one essay and another one that the college tells u to write?</p>
