Some information on Wharton PLEASE!!

<p>Although i have been surrounded by people, many whom have attended top US and UK Universities all my life, i have little knowledge as to what is it exactly that the US universities seek for in the applicants other than passion. Hence, i was wondering if your could provide me with some information as to what exactly is it that the Wharton admission officers so that i can prepare for it. By the way, im from Singapore, so im curious as to whether it would be a disadvantage. Thanks</p>
