Hi Folks, I appeared for the test yesterday, I scored 944. It was great. I prepared using Cisco Press book (Odom), CBT Nugget and Todd Lammle (I love his subnetting method). This is my first certification ever and I was nervous but after 15 mins in, I was all set and it was great. Now I am going for vacation for 10 days and will start studying for CCNA after that. I am interested in Security track, Am I eligible to appear for 640-553 exam?
