Difficulty: I guess this is relative, but...nah not that bad.
Length: I was in and out in 20-25 minutes
Questions: I think there were four. you miss one, you get a second chance at another. They also are...umm...helpful, if let's say you're not quite getting everything they are looking for in an answer. Best strategy: just keep talking and eventually you'll get there. Study the statutes, know the lists, use tricks to remember the lists. I'm hesitant to put anything else for fear of the board coming and finding me for posting about it on an anonymous board (laughing...but also not), but for real. don't sweat it.
