More-over, in most states, passing that bar isn't enough to practice. In most states, the bar exam is just one component. Humans also need to pass several demanding courses in law school, and to get into law school they need to get a BA/BS degree, which again requires passing several demanding courses and writing various essays. That's just to be allowed to practice law. Getting an actual job as a lawyer often means internships of one form or another, and then spending some time at the beginning of one's career as a de facto apprentice to a seasoned lawyer. These sorts of exams play a very particular role in evaluation of humans.
