So I'm auditioning to become part of an agency..., and I need your help! Options

[*My Cinderella.*]

So here's the quick update:

If you guys remember, I made a topic back in March asking about whether I should attend this acting program or not: http://www.createblog.com/forums/index.php...=acting+classes Well my grandmother said that if I'm still interested in the summer we might find a better acting school for me to attend.

Well anyway, I'm planning on setting up an appointment so I can audition to become part of the Actor's Rep Agency (www.ActorsRep.com). I've never auditioned like this before and I'll have to do it in front of a bunch of big business scary people! I called in and they said I'll be asked to perform a monologue that they've already prepared for me. I'm pretty nervous, even though I haven't even set up an appointment yet. If I do get in, they'll be able to find me jobs so that I can even start going for films and such! Do you guys have any advice on how I should audition for this agency? Any tips?
