MC was very difficult. I would say around 20% of it I had never heard of before! 30% i found very very tricky from the information on study guides. And the remaining 50% was not even easy except for 5-10 questions!!!
Site design vignette was at the same level as ncarb sampl vignette. Straightforward!
Site grading, however, was a but tough since the space to place the building was tight but doable!
This was my second exam of all so I may not be that experienced!
What i studied: ballast, kaplan, nalsa flashcards, jenny's notes, some of the audios from arr prep ( not recommended as much for this test), dorf vignette videos.
Good luck.
