Easy, Easy, Easy!!! (and inexpensive)
This was the most user friendly traffic school I have ever used. It was very inexpensive and gave you optional upgrades only if you were interested after you passed your final. They charged only the amount they promised on my credit card. My place was saved right where I left off after logging off. You can review all material and quizzes at any time after completion of a section. There is a usable study guide during the final exam.... (you won't need it if you complete all of the sections). Very Satisfied with TrafficSchool.com!
