But that's beyond the point, right? The question is whether it is accessible. Which for some states it is, and could be done by reading material. The same can be said about programming and software development.

My point precisely is that you can't pass just by "reading material". It is too hard for that.

Test being difficult is not a problem, we want our lawyers to be competent, after all. The more important part is if it is fair. In Poland bar exam had been famous for near impossible questions, which were only answered correctly by applicants that knew them in advance, which typically were family members of already practicing attorneys/judges.
