The course had some ups and downs, but it was a good challenge and I did it! I learned so much and I never knew I could do this kind of course. I have gained so much knowledge now from when I started.

Great course. It is great for beginners and for people that may have forgotten a thing or two. The way it was taught makes it so much better than reading man pages or something else as dry and boring.
