I was surprised how different the actual exam was from practice tests. I passed with a 823 and it took me 23 minutes out of the 1.5 hours I was allotted. I used Mike Meyers book from a recent networking class that I took, but I mainly used the Testout Labsim software along with Kaplan software Self Test Software. I found Testout labsim software to be invaluable in my studying. I crammed for about 4 days for this test. GL to all who go for it, you can do it!
