All I can say is WOW! Trying for the second attempt was hard for me. Being 51, the memorization part of it is not easy. I pushed on, I learned from my mistakes and focused on the formulas and memorization. EaC, EV, all that stuff. Now my first exam was a Gozilla of an exam, I know they are ramdomly generated but I had 9 network diagrams to create. This exam today, 2 simple ones. 

I felt the questions were solid, I was crossing my fingers at the end, 3 minutes to spare and when I saw "PASS" I was so blown away.
