Got the same score of 623

This second time I felt so good about it. I knew all the devices, what they did, protocols, ports, acronyms, etc...
The simulations were cake also.
I think I got stumped with the "choose the best" option type of questions, plus those long paragraph questions.
My school is going to try to get me another free retake.
I don't know What I should do differently this time to pass.
My materials were total tester exam questions and the Cert guide book.
