On the application it says include all schools you've attended then i should?

I attended like elementary schools in the US and in Korea. The app specified for me to write down all the the schools i have attended in an english speaking country. Do i have to write down all the elementary schools i attended in the US since i changed frequently. It seems sensible only to include the high schools i have attended but i just want to make sure. I know this sounds stupid but i appreciate ur advice. thank you.

<p>If it says 'secondary schools', or tells you what grade to start with, then only include those schools. Otherwise, list grade schools.</p>
