I think my advice to you concerning the CCNA is to just simply relax
We all get test anxiety on varying degrees. I have seen you ask over and over that very same question you just asked above. I also seem to remember you saying you were scoring mid 90's on practice exams.
What you need to do is stop worrying about what you think you don't know, and focus on what you have learned. When all is said and done the exam is not going to be made or broke on you cramming every single area of knowledge ito your head with perfect recollection. You are far more likely to fail becuase you are so bloody nervous that you can't remember the basic stuff that you know you know.
IMO the tests aren't designed to be hard... They are designed to test that you know wtf you are talking about; they test for understanding.
So go for a jog, meditate, hit the gym, eat a bowl of jello, smoke a fatty... What ever it is that you do to relax and gain focus. That is what will help you pass the test.
That's my two cents
