I need to find a free online practice DMV driving permit test for NC?

i dont want to signup or register 4 anything but if i have to i will as long as its FREE. nothing i found was free and there is no way im paying or my mom will pay to take a practice test.|||I got my permit last month and it wasn't that hard actually. Just study your signs, and the test is everything that you learned in driversED or atleast heard about. Although there are statistic problems as in percentages. You get to miss 5 questions so don't stress too much over it.... i missed 5 =]|||The best bet is to study ur drivers ed books the and the test is really pretty easy as long as u know ur signs
