What would casue rapid results to not be in? well after 48hrs

Two of my nursing school friends took their tests recently. One took it on Saturday the 13th and she got her results already from the BON. The other took her's (same facility) on Friday at 8am. She still does not have her results. We are in FL and they do allow rapid results. She is FREAKING out that she did not pass. What are some reasons that one who took it after the other got her results but the one who took it earlier did not get her results. She said that it shut off after 85 ?'s (PN exam).

Thanks for any help. I did tell her about the PV trick but she is so nervous that they will fail her if she did not already for checking it. She is a bundle of nerves.
