I probably would have my driver's license now had I not thought about the hassle of getting one. The idea of studying page after page just discourages me, especially when there's no assurance that what I study would be part of the test. I don't want to fail and come back to retake the test again.
Thanks to the CA DMV Practice Tests for creating a remarkable study guide to make things easier for everybody to pass the test. The materials are available at their site. It's NOT free because these people who made these materials put their effort into making everything possible for you and me to pass the driving exam on the first try. They also offer online practice tests which enable you to familiarize yourself with the setup of the test. This would help you feel more comfortable when you finally take the actual written exam.
I know that everybody wants to pass the driver's written test on the first attempt. The DMV practice test is a proven tool in succeeding at that goal. Life is a little bit easier if there's help close by; and if you are not happy with the result, you are guaranteed to get your money back.
