USC Art Supplement Visual and Written Sample questions

<p>Herro, so I finished my creative portfolio, visual sample, and have everything else for my USC app completed except for my Written Sample and SCA Personal Statement. For the written sample can I just write about my visual sample (or relevant) or does it have to be a completely new story? And also, what are they looking for in my SCA Personal Statement? How does it differ from the personal statement that I used for the Common App?</p>
