Advice on Waitlisted Transfer Student please?

<p>What am I supposed to do at this point? Do I send a letter in expressing how much I want to go to Columbia? How can I make it so it's not the typical cliche letter? Also is it supposed to be in business format?</p>

<p>What else should I send? I haven't made any achievements since my application in March...</p>

<p>I made a couple of speeches last year during my senior year, including a graduation speech. Should I send that in ? Or is that way too dated? </p>

<p>Thank you for your advice!</p>
