Cover Letter... Urgent...HELP!

<p>Hi!</p>

<p>My school gonna send an envelope to colleges that I am applying, enclosing
Teacher rec, Counselors forms, Transcripts, my CV, school profile and some other stuff.
I am supposed to write a cover letter for this package.
But my school is the one that will actually send this envelope (even if it contains my CV).</p>

<p>So, what should I write to this cover letter. Should I write it on behalf of my school and then have my principal sign it? Should I write about myself, u know a typical cover letter? Or both of them????</p>
