Just for the record, I have taken this exam twice before and failed, once in 2014 and then more recently in Aug, 2015. I had a lot going on in life and was not able to study on a consistent basis. Took a break basically. Then starting in Jan 2016, I picked up the books again, went through everything once. Went through the CBT nuggets videos twice. I did a few labs, just on topics I felt weak in, to get a better feel for what the topic was about.
I also credit my experience as sys admin at my newish job, I am responsible for 4 servers and about 35 client workstations. That helped too.
Studied pretty aggressively in the last 2-3 weeks prior to the exam, then on exam day, did not think about the "exam" at all. Went into the testing center with a calm mind, and was mentally prepared to fail. I actually purchased the booster pack for $200, which is funny because I wont be needing the retakes now, but the extra $50 insurance was worth it.
I am so happy right now! 

Onward, 411 here I come!
