Need help filling out EC's on Common App

<p>Hello,</p>

<p>So for one of my EC's, it involved signing up for shifts whenever you were available, so there are weeks where I have done 0 hours and there are weeks where they go to 12. So how do I fill out the section for hours spent per week and weeks spent per year? Any help would be appreciated. Thanks.</p>

<p>Take an average for everything.</p>

<p>Average it out.</p>

<p>OK thanks! I’ll just take the total number of hours and divide it by the number of weeks.</p>
