The bar exam using an abstract system (that may not really exist in reality) vs specific state law systems seems just fine, as long as the people smart enough to pass recognize that. I suspect they are. But the bar also tests quite a bit about the concept of liability, the essentials of contract, constitutional law, intent, and I'm sure a bunch of other topics. Are those of so little value that it's worth ditching? Is 1/3rd of a working year (675 hours) enough to cover all those topics? What if the attorney is an estate planner? Or a litigator? It would seem this risks making the minimum experience of a given lawyer potentially more lopsided.
