I got a 712 and needed 804 to pass. I know a lot of the questions I got wrong were based on some form of subnetting. Not the best attempt, but I know I can do better. Not sure what my score means as far as how many question I missed passing by. Lol
712 is not that low. I visit the techexams forums a lot and a lot of people that fail get a lot lower than 700. You are definitely almost there. A few more weeks of studying should do it.
