Hi! I'm a current distance student. You're going to be watching a live feed of the class as its happening. We use Skype to type in questions/contributions/take attendance. I like to use the Skype app on my phone to ask a quick question if I have one. I haven't had a class yet where I've needed to "call in" and use my webcam. BUT I did have a class last semester (neuro with Bratcher) and during class we had to work on group projects during class time. I've had other classes where I missed because of work and just watched the recording of class that evening. I haven't taken summer classes but I've heard its really intense so just be prepared to be able to ask a lot of questions and potentially rewatch lectures.
