I wish I had read these reviews before I signed up my 2 teenagers for this course. It was recommended to us by another family who had luck completing the course and receiving a Colorado drivers permit. However, the experience we are having is the opposite. We are unable to proceed to the review/quizz section of the tutorials and receive a server error. I have phoned, emailed and tried live chat with no response. I am going to the Consumer Affairs Dept in Colorado and the BBB to register a complaint and hopefully no-one else will get taken by this company.
