Explanation necessary?

<p>As I am not from the US I have two questions regarding things I incorporate in my essay.
I'm talking in my essay about an organization that has no comparable counter part in the US,
so should I explain it in my essay or is it sufficient if I have already done it in my activites list?
The next thing:
Do you think the adcoms are familiar with the concept of polyphasic sleep?
Thank you kindly, </p>

<p>If you're talking about the organization in your essay, you should describe it in more detail. Also, I doubt that the adcoms are familiar with the concept of polyphasic sleep.</p>
