Do not use Pass4Sure! It's a waste of money.
They guarantee that you will get your money back if you don't pass, but actually, they don't give you your money back, and blame the reason for me failing was because the questions changed... and I studied my butt off for 4 months. Their study guides are horrible and testing material is outdated. Stick with TestKing!
I used Pass4Sure to take one test, and failed.
I used TestKing for my CCNA and CCNP exams and passed all of them with flying colors!!!! DON'T WASTE YOUR MONEY ON PASS4SURE!!!!
