Applying for a music program

I plan to study composition in college. However I'm not sure how to record my scores to a CD format. So how would I go about doing this?

What have you written your scores on? If you wrote on Finale and have GPO you could just save you scores as an audio file. You could also make a pdf of your scores and send along an recorded version on piano. Depending on what they want, you might not need to send an audio file. You should definitely convert all you scores to pdf if you want to put them on cd and be sure that the college will be able to view them.
