Passed LX0-104 a couple months ago and forgot to add my achievement here. The exam was actually a bit easier than LX0-103, which I thought was quite a bit harder than my CISSP exam. I now have CompTIA Linux+ and LPIC 1. I really enjoyed learning about Linux on Linuxacademy. I did have to combine the Pearson book. That was especially helpful for the first exam and to clear up some concepts that were in the LXO-104 videos here. There was a time when I knew practically nothing about Linux, not anymore :) I do love the structure provided here on the Linux OS. Thank you guys and best of luck to anyone going for this course. It's an excellent course.
