The ability to have the course self-serve, allowing students to register themselves for an online class when it’s convenient for them. I like that they have an option to provide a virtual classroom experience through webcam or a microphone. There are times when the audio cuts out and I can't hear what's going on in my lecture. It seems to happen most often when I'm speaking directly into a microphone. Also, sometimes the video doesn't load right away and I have to refresh the page to be able to continue watching the content. This isn't too much of a problem because the course itself is very interactive and engaging, but it would be helpful if the audio/video worked more consistently. I highly recommend taking this course! I was looking for a way to enhance my existing skillset by adding new ones to my resume. This.
