autobiographical sketch

when teachers or counselors ask for an autobiographical sketch, what are they expecting? 500 page book or 1 page summary?

<p>A page......</p>

<p>so like, do you put "my parents are x and y, born in these places, and graduated from here..." and "my passions are a, b, and c" and "i've done this, that, and more"?</p>
