When is your test?
I took mine today and passed with 91%. I found the CWNP practice tests extremly beneficial.
My main tip would be to read every word in the question and answer, don't scan the answers as you will inevitably rewad what you THINK should be there, which may not be what is ACTUALLY there. I found on some questions there were more tan one possible answer, untill I re-read it and took in all the words, then bingo!!!
