Product is okay. Much of it is simply listening to someone read text out load while looking at the text. There is no way to move ahead if you are done, so not only is it boring, but you end up wasting a lot of time waiting for the audio to finish. Also, many of the lesson timers are out of sync with the audio, even though you have finished there is still 1,2,or 3 mins left to wait for the timer. The sections with video are better. On an iPad or computer if you fail a quiz you need to go through the entire module before trying again. However, on your phone you can not only take the quiz again immediately, you can also see the questions you got wrong. My son failed two of the quizzes so wasted a lot of time redoing modules until my wife realized the phone worked differently. Consistency would be nice. Over an okay experience.
