Help with OCN exam

[WSK]

I am taking my OCN in 2 days and I'm completely stressed out. I've been studying, but the practice tests I've taken have SUCH specific questions. How am I supposed to know it all?? Any advice?

Hi, I apologize that I am just seeing this but was wondering if you have retaken the exam and passed it? I hope that you have, if not please reach out and I can possibly help.
