Pretty good program, but I had a few issues. One very annoying thing while studying the material is the required time necessary for each page, as often it is too long, up to 50 seconds in a few cases, where you are required to stay on the page even after the video is over. Another thing was that for one module I received 70% on the quiz and was then given the option to restart the module which then FORCES you to go through every video again with the time constraint which is awful when you have to then spend a whole hour doing it over again. The test also doesn't tell you which questions you got wrong so you can't figure it out for the next quiz.
