Waste of time - materials were supposed to be based on the most current textbook. The WORST possible thing they couldve done was remove my access to the test simulator. It was nice to practice with questions, but they removed my access to the simulator, so also useless. Horrible company, no ethics and even worse customer service. They genuinely do not care. The information is somewhat reliable, but videos did not play with audio and have no captions. So paying for those was useless. I downloaded a PDF study guide that is semi helpful.
