The quizzes at the end of each module sometimes asked questions from future modules I have not yet completed. The multiple-choice answers are often worded poorly leading to incorrect answers. If you fail one of the modules instead of being able to review the information and retest, you have to retake the entire module and are still required to wait 1-3 minutes on every single question which is a total waste of time. It says that this course takes 3 hours, but it actually took me over 7 hours to complete. The positive: The videos and narration are well-made and helpful. I haven't taken this course from any of the other providers, so I don't know how it compares, but I would not recommend this course to others until they make some needed changes.
