You are "late" in terms of getting most of the pre-December interviews, but you still have a strong chance of getting post-December interviews assuming you have strong GPA/DAT/EC's. Send your AADSAS asap!
I think what OP meant is when his /her app is no longer on hold (aka they will soon receive the official dat score or LOR via aadsas, hence the app will be complete)? In that case the school can review the OP's application asap. Correct me if i m wrong, though. Some schools have already sent out interview invites, so isn't the earliest time to submit from scratch. I am in similar shoes.
