@hometownmedic5, the online course's lectures are released on a weekly basis, and the projected timeline for both the in-person and online classes that are on their website is how long the course itself will run. So, it's not done at your leisure, per se.
Essentially, you're given a course start date then the first week will begin and you're assignments (along with the lecture/s) are given to you to be completed by a certain date before you can move on to the next week. If you begin to fall behind, your grade/ credit for that particular week, and overall class grade/ score will decline as well; IIRC, you need an 80% overall to pass the course. Each week should contain an article, discussion board, lecture, and exam on a specific critical care topic.
He also does (did) live discussions on topics that many newer providers may, or have struggle/d with (e.g., ventilator management, hemodynamics, etc.), but this all seemed to depend on how involved the class was overall, and in general.
PM me if this isn't a specific enough answer for you.
