Many people have already taken this or one like it at some point in there life, but always good to try and see how you do.
Below is a link to a 30-question test to see how well you know US Laws. Not exactly grade-school level. Give it a shot, and see how well you do!
Supposedly 96% of all high school seniors FAILED this test ... AND if that's not bad enough, 50+% of all individuals over 50 did too! Take the test and be surprised at what we don't know.
