Taking NCLEX-PN in a weeek!

Ok...soooo im completely nervous about taking NCLEX on the 22nd! This will be my second attempt. The last time i took it was in January and I graduated in October. I have been studying everyday for about 2 months. I still feel like i dont know it all! I just dont want to fail again. I have horrible test anxiety. I mainly have been focusing on medsurg..i still need to look over psych, and a little pharm...any suggestions or advice...words of encouragment?, what to focus on when i read all the questions? At this point with only having a week left (Ive already changed my date numerous times) i feel like all i can do is take a deep breath and try and focus and stay positive. I mean no one is ever going to "know it all". I need to pass this time though so i can apply to the RN program this semester! Ill appreciate any comments thanks!!
