The way the modules are set up price to be repetitive and difficult in the sense that the time till you can click to the next chapter in many cases made it so I had to Re watch 10-30 seconds of the video slide before I could click over to my next approved module. I found this very frustrating. I run on a high functioning computer so I know it was not due to poor internet or loading quality. I also tested on a different internet connection and in another case a different computer all proved to do the same. I would recommend fixing this glitch because otherwise the course was informative.
