<p>Let me help you feel better. I also signed-up for the Sunday ACTs on Sept. 17th thinking that there was no difference between those and the Saturday ones. Then when I got my admissions ticket it said that Sunday centers are only for religiously affiliated people and whatnot. So I called ACT and asked a lady what could be done about this. She simply told me that I could change test centers and that it would cost $20, and then very slightly implied that I should just go ahead and take it Sunday because test centers do not check for ANY type of verification. Getting the hint, I went to my test center on Sunday and everything was fine. It actually looked to me like most people there had no religious affiliation at all and just made the same mistake I did. </p>
<p>Hope that helps.</p>
