state test (cna)

hi my friend and I recently took the cna state test and I fail my skills and she passed but she told me I did good but she don't understand why I failed my question is can the lady that's grading you on your skills tell you if you messed up if you didn't notice it and make you do it again? cause when my friend did the skill of transferring a resident to a while chair she did it wrong and the lady told her to do it all over again was that even allowed? I just don't know I somewhat feel like the lady had some kind of thing against me idk im sad I fail probably that's why im over thinking things out
