Before and After graduating from my school up to now that am doing my Masters in Information Security, I had never ever attended such lecture from any professor in my entire life, It was really, really AWESOME.
I really liked that due to the one who is giving lecture have a good knowledge of the topic, Huge love and thanks from Afghanistan, for sharing such lectures.
