I messed up

I got an audition for campus choir yesterday. I was too excited that I can't chose what song to sing. I even changed the song a minute before they called my name. and the worst thing is I messed up my interview... T___T they asked me "how sure you could make it and join this choir" I was shaking and thought every single number that I could say but I said "60%" .... and I felt sad about it. I should said more! hmmmm...
I hope I could get in there. I just really really want to join them. I hope I could......... now the last thing that I can do is waiting and pray
