“Throughout my years of studying computer engineering from 2012 to now, after paying for CBT nuggets, INE, and CCIEorDIE, Iv’e never came across an teacher that actually teach through varies kind of methods. Including “live” Wireshark as he teaches to show the behind the scenes (its like once you watch the movie you get to see the behind the scenes.) which gives you the full complete understanding. I learn topics in a day! Sagar Dhawan teaches at a comprehensive level. He is a Comprehensive Instructor. I am very great full for taking the intuitive to give him a shot because I was reluctant do to many tries with varies teachers in the past. Much thanks to him and may he be your Instructor as well.”
