Where can i take a practice permit test?

i live in arkansas so i need a test that was designed for here, and i need it to be free. does anyone know where i can do this?|||try this site, it's general and fitting for most states. I too live in AR and I've looked in the book and many of the questions are word for word from what comes in the study guide. I have Vol.1 Edition 4 the red one so I think it's the latest. But anyway try this link
