Including Gap Year on Common App

<p>Hello, I am currently on a gap year volunteering in Ecuador investigating organic coffee farms and the effects of fair trade. I am trying to best incorporate this into my common app application. On the education section there is a box you can check off to state you took a gap year and the help center states If your progression through secondary school was or will be delayed or interrupted in any way, you will need to provide an explanation for each incident you have selected.
What I'm wondering is if there a specific section to write this explantation or do I incorporate it in the common app essay and the supplementary essays? Thank you for your help.</p>

<p>Please somebody give me an answer</p>

<p>If they don’t supply a place, put a description of your gap year in the Additional Information section. You may choose to talk about your gap year activities in your essays, but the actual explanation belongs in Addl. Info.</p>

<p>Thank you!</p>
