important question about my essay

<p>i just got some feedback from a teacher today. my essay is basically about self-discovery and open mindedness. my teacher suggested how i can conclude it with what each specific college has to offer for me to grow as a person and student.</p>

<p>so my question is...can i change the essay on my common app for each college?
and i'll obviously be careful, lol. i won't make the mistake of saying how excited i am about school X when it is in fact being submitted to school Y.</p>

<p>i'm just looking to change one or two sentences.</p>
