Great class, difficulty navigating lessons however

I just completed the class and thought the materials and presentations were excellent. The instructors seem to anticipate where I had questions and lo and behold, they answered most things shortly after. I have to say though I found accessing the lessons a bit rough. Most of the videos did not have a “next” button (only a repeat), while some did, so I had to manually advance the class from the outline. Also, I would watch videos on 1.25x speed, and each video I had to set that for each video I watched. I also took the practice exam but paused half way in, then when I went to resume, it had cleared out all my answers. That was frustrating. I would still recommend the class though!
