Experts on “Gaming the System”?

There's been some opposition to requiring lawyers to pass bar exams.

Wait a moment… I thought the opposition to standardized tests was based on the idea that the people who passed were experts in “gaming the system” instead of the content. Isn't the content of law (in practice, if not in theory) a matter of “gaming the system”? Apparently, people who pass bar exams merely memorize facts instead of knowing them, a distinction so subtle it may as well be nonexistent.

On the other hand, maybe that means requiring bar exams is unnecessary. Lawyers who didn't pass a bar exam might not have enough customers to matter.
