I passed my icnd2 yesterday 813/811 on my first try. I passed the ICND1 with a 906 after failing it twice! The mistake i made the first time was only studying from one book. or the ICND2 i read and re-read 2 books. Lammle's book and Odom's book. These two together should be sufficient to pass the exam. Didn't really do no videos but I did do some labs. I am deciding whether to go for my CCNP or my SSCP because I am specializing in both network and security.
