Our online courses are not lecture-based, they are “asynchronous.” That means you can log in any time of night or day to study, and to post in the forums. This way people in different time zones can participate at their convenience. Some courses do have course-wide webinars, and these are timed so that a majority of the participants can attend. We then record and post the videos in the course so those who could not attend can watch on their own time and benefit from the discussions.
