So I have almost finished reading ICND1 by Wendell Odom's , doing labs side-by-side, watching videos. I am giving my self a month before I schedule the exam. Should I go through Odom's books again or start with Todd Lammle's ICND1 book? I did do a few chapters earlier of Lammle's book, but found WO's more easier to follow, and liked his flow and classification of chapters better than Lammle's. Should I bother with Lammle's book or read Odom's again? I will continue of course doing a lot labs and watching videos again.
