Starting to get pretty nervous that I will see questions I'm not prepared for on my Network+ exam tomorrow. What is the likelihood I will be caught off guard by material I am not familiar with? Has anyone else had problems with this in the past? Thanks!
UPDATE
I passed! 810/900. It took me a little less than an hour to complete the 100 questions and then review each question individually. Unfortunately, at a testing station a few down from mine, a woman started to flip out during the middle of my exam. They say nothing about this situation in any Network+ preparation guides

. I'm crazy pumped right now, thanks to everyone who posts on this board for your assistance!
