I was a bit anxious about this exam so I avoided it for awhile, but finally got the courage. I'm definitely not the proudest of my scores, but I passed. I got a 550 for the 103 and a 590 for the 104.
Honestly, I thought the first was easier, but I seemed to have got a lower score. Go figure.
Some advice for anybody taking these soon. I'm with WGU, so I used the material they provided, but in addition to these I also used CBT Nuggets for the videos and I practiced with what must have been 10 different instances of virtualbox, my favorite being CentOS 7. I used Mint 17 for my personal laptop. I made it a habit to use the command line every single time I wanted to complete a task.
The exam for 103 had 2 fill in the blanks which was nice, but 104 must have had around 15 I believe. I was very unprepared for that because I was expecting only a few. I would have passed with a much higher score for 104 if I'd study more.
Last thing, one of the mentors from WGU posted a share from google drive with a massive amount of practice questions which can be found here https://drive.google.com/folderview?id=0ByXMDcxlNpReSnViaWp1XzBSSlU&usp=sharing
These helped me A LOT. LX0-103_104.Study.Questions was the most helpful. Spend some time with these and you WILL pass!
Good luck for all you future linux certified peeps!
