Which ECs to list? (gap year)

<p>Hi all. I'm currently in my gap year after graduating from high school in June. During my gap year, I will be working full-time at my school. I have a lot of informal activities I am doing during my gap year (teaching myself a language, etc.) as well as some formal things (coaching/advising groups at my school that I participated in as a student). So, which ECs should I list? Informal and formal, or just formal? Or should I leave all of my gap year activities off of that section and just mention all of them in my required gap year essay?</p>

<p>Thanks so much, and I would be happy to answer any questions of yours that you may have since I've successful ly survived the application process once so far. :)</p>
