<p>When they say to briefly elaborate on one of your extracurricular activities or work experiences, do they want you to tell a brief story or just a quick explanation or what..? What would be best?</p>
<p>Its up to you :) You can do whatever you want. If you think a story will tell adcoms more about your extracurricular, or if you just want to jot down a few sentences about what you did in your EC, whatever is fine.</p>
