Reviewing for OCN Exam

I am signed up to take the OCN exam this month for the THIRD time! (and no, not just for fun!) I am real nervous about taking it again and need any advice or study help possible. Hoping to find someone out there that would be interested in reviewing some with me. It always helps me to talk about or discuss things rather than just reading! I am just sure that I am going to pass this time, I have to!! Let me know if you would be interested in online chat or something. Thanks!
