I recently had to complete courses on your website and had an overall poor user experience. I had several videos I was assigned to watch under my “to do list” so I started watching them. I eventually noticed that I had not been watching the assigned videos but related videos instead. It would make sense that the next assigned video would play after one is done watching the previous like a Youtube playlist but that is not the case, in fact the page only shoes related video on the sidebar and under Next Videos which neither are the ones that were assigned to me. This is probably something that has happened to others and it could easily be fixed to improve the user experience.
