 The main benefit is that it's convenient for people, so I have a number of students that are in the Seattle area, and so they only have to come up to campus five times a quarter rather than, or whatever I require, rather than ten times a quarter. And that leads to a learning benefit because if we didn't give them that access, then potentially they wouldn't even be in their class, granted maybe they could take the initiative to learn on their own, but we're all busy and we like deadlines and timelines because they help us regulate our, and manage our time. So I would say convenience and access are two main things. And along with that, then, by providing access to students, I think we reach a more diverse population who, again, wouldn't potentially have the opportunity to be enrolled in the class, and that makes the class richer, in my opinion.
