Prof Whitebread says there are 3 levels of knowledge and understanding of the legal materials on the bar exam.
1. The Glib understanding where you've seen the material and get some of it
2. The point where you understand the problems with your understanding and can identify where you're lacking.
3. The point where you've overcome your problems and have a true understanding of the material.
He guarantees that you only need to get to the point of glib understanding and that no state's bar can ask anything more from you. It seems like just the opposite, but if you just think of a few lawyers you know *cough*Monica Goodling*cough* this starts to make a lot more sense.
