There is no big magic in clearing Network Security Engineer certification exam, i think. It is just that one should know the right path. My professor in college suggested me to take PCNSE simulated tests online. I took his advice and it helped a lot. The syllabus is covered gradually with mock tests but i did not have to revise. I tried to score 60% in mock tests and in the actual one i got 70%.
