I (Dung Lai, 101467732) do this subject in semester 1 2017 and get 75 final score. FOR ME, this subject is hard to learn (final exam) and easy to fail (final skill exam)! Pass rate is 65-70% so be careful. The content is pretty abstract, you might have to imagine and accept the fact that they told you without really understand it. Lecturer and tutor are helpful. Lectures talk pretty fast and the contents he said is very condense. There are practical parts (skill exam, case study) and theoretical part (final exam). I get max point for the practical parts so you can ask me for help, small tutoring session with me and you will get the point very quickly. Remind yourself that the final exam is not gonna be easy and it requires your understanding of lecture content, the practical knowledge will not help much except the subnetting part which is free point.
