<p>In my main common app essay, I elaborated on the activity that is the most important to me. However some schools like Columbia have a supplement that asks you to "elaborate on the most important activity to you". Should I pick a different activity or reiterate the same activity? </p>
<p>The college essays are meant for colleges to know a student as much as possible outside of their academic scores and list of activities. So pick a different activity.</p>
