additional information

<p>What do people usually put in the additional information section? </p>

<p>I attached my resume but I realized that for my extracurriculars, since I tried to fit everything in one page, I did not include the years I participated in it.
So other than the 7 extracurriculars I had included in the common app, I actually didn't have the years for my other activities. </p>

<p>I was wondering if maybe I could send colleges a correction type of thing with a new resume that shows the years of participation? Should I do that and is that possible for most schools?</p>
