Mailing Address vs. Home Address (if boarding school)

<p>Hi, I was just wondering, if I go to a boarding school, do I put my school address as my mailing address and my home address as my permanent address? I'm asking this after looking at the MIT application but I guess this would apply to any..</p>

<p>Ok I also have some other small questions about format...</p>

<p>1) When it asks for Place of Birth (City/State/Country), and mine is D.C., would this be the proper format: Washington, D.C./United States</p>

<p>or... Should it be District of Columbia/United States
or U.S.A.
Which do you think is better?</p>

<p>2) If a sibling has received more than one degree, should I list them all?
For example, "BA and MA" or should I just write the higher?</p>

<p>3) I know this sounds like an obvious and stupid question, but what do people usually write under the "If you feel the need to clarify your answer to any of the questions on this form, please use the space below" part?</p>

<p>I think that's it... Thanks! These are all from the MIT Part 1 app btw.</p>
