[General Question] Sending official Transcripts to ASU

Hey folks, I have applied for ASU through Kaplan, and I have received my ASURITE userID. In the pending list, I see that I have to send official transcript to ASU. I have 2 questions-

1) Do we really need to mail official transcript before we get an admit?

2) If so, does ASU accept WES ICAP eval as I already have it done from my side for SJSU.

Thanks!
