Pretty easy, overall.
Honestly, this is a very easy course. I personally had prior knowledge of unix systems so it was even easier than before. Best part is CTU has recently converted this course to InteliPath so its even easier than before. To give a perspective of how easy it is, I ended up finishing this entire course in less than 10 hours in 1 week. Just to give people a rough idea of how it works.
Like I said I had previous knowledge in the subject so I did not really learn anything but I did refresh my memory on commands that I haven't seen in a while.

Advice for students:
If you can sit down one weekend and finish all of the assignments jsut make sure to go back every 15 days so the system does not auto drop you. Also notify the professor when working ahead. Most professors like the diligence.
