<p>"In the space available discuss the significance to you of the school or summer activity in which you have been most involved."</p>
<p>the extracurricular i want to talk about is not related to school but takes place during the school year. so technically its not a "school" or a "summer" activity? is it okay to talk about? what should i say?</p>
<p>Yeah. It says school or summer activity. So I guess you can write about that is not related to school. If I were you, I would write about my volunteering or like summer camp that I had went to in the summer. Write about something that might really appeal to the admission committees, For example, something that has to do with academically, how unique was that activity was or how that might helped you in such ways in your life etc. Good luck to you iz1212 (:</p>
