Hello to everyone who has tried this challenge.  I have tried all of the solutions below and used 2 or 3 different playgrounds, and I still can't get this challenge completed.  What else can I do? Is there a video link? 
Just failed my Admin 201 test. I'm so angry and frustrated. I took a ton of practice tests and did well on them. The actual test was nothing like the practice test. The actual test was ridiculously vague.  Anyway, does anyone know where I can find practice tests that are actually up-to-date? Any suggestions on how to study that doesn't cost a billion dollars? I'm just super frustrated and angry right now. Thanks for the help.
