1) If I don't pass the audition, does that mean that I don't any chance of getting into the CP
At the time of this writing, you have 2 Yes's for this.
However, I'd say not necessarily. They will consider you for other positions if space is available, but they aren't holding a backup for you in case you don't make it through.
It was either on these boards or another where several people who were cut from auditions were not offered another position because they were full.
Now this could be that they were full-full (everything) or that the other positions that they were interested in were full and they weren't willing to do any of the positions that they still had open.
