<p>I have been selected ED ... Now how do I withdraw other apps... ?
I am writing them an email and sending them a signed letter through regular mail .... Will this be enough ?</p>
<p>Yes, that is enough. Congrats, btw!</p>
<p>Congratulations!</p>
<p>That should be enough. Call the schools tomorrow during their business hours and make sure, just in case.</p>
