Attaching supplementary materials to an application

<p>I have spent over a hundred hours coding a computer program, and I consider it very impressive. I want to send my program to a select group of colleges that I already know are extreme "stretch" schools. I want to send it to each school's computer science department if possible.</p>

<p>How would be the best approach to send it in?</p>

<p>Anyone have an idea?</p>

<p>I m going to apply an science supplemental material also.Maybe u can send it by mail.I m thinking also to send it by mail because I am going to send additional reccomendationletters too</p>

<p>I hope I was helpful.:)</p>
