Registration and Audition

I am only half asian, and by asian I am half Filipino. I would like to try to become an idol. I understand how hard it is, but I have to start somewhere. I don't have much experience with dance, in fact I am very bad at it. I have self studied some korean and have learned  hangul and now I'm working on Hangul. I'm thinking of registering for the Korean,Dance, and vocal. I am not very good at dance yet. I see there is an audition does this mean I have to be good at auditioning to get into this program? I also am not that very good at korean yet so would I have to audition to get into this program? I speak fluent English and tagalog, and I am learning korean.
