Piano Answers

I’ve been playing the guitar for seven years, & it’s a lot of fun. However, my dream is to compose piano music for video games and/or release my own music.
I have a piano at home, but can’t play it very well yet. I heard that at my school of choice you have to audition in order to get accepted into a music composition program. Is it possible to get a music composition degree without being able to play the piano well at the beginning?
