So I'm not sure if you're still doing the Satellite campus version (4 months straight through finishing up Common Core), and it will just be held on blackboard?
Or if you are being pushed into one of the TASS versions (mainly Reserve folks with some AD, divided into three phases, done in one two week session, eight monthly weekend drills, and another two week session).
Or is you are being pushed into the pure DL self-paced version (if you are doing this version I'm sorry, I here it is terrible).
Either way I can comment on my experience doing the TASS version, online via blackboard. They have had us meeting on Blackboard Virtual Classroom because of COVID. It's very similar to doing Zoom or Google Classroom. They still have to meet in class from 8-5 each day and go through each of the courses, have discussions, do briefings etc..
So there are very few changes from the in person version. It is a bit more convenient in to be in your house doing it, but you probably do lose a bit in the fluidity of the discussion.
As for the course material, they make claims about it being graduate level, this is a joke in my opinion. A portion of it it similar to an undergrad political science course on national security, the history portion is decent but still very much at the undergrad level. The leadership curriculum is puzzlingly simplistic. If you have experience in the Force Development then the force development block won't be anything new.
As a whole the course does take a fair bit of time, but I would not call it challenging. There is a lot of what seems to be busy work, and the mandatory writing style that they make you use is horrendous. Expect to spend a lot of time doing the reading and some of the assignments, but they focus more on form than content.
I can't say I've learned much of anything of value in the course. It seems to me it's just a hoop to jump through. That's my take on it, others may have a different view.
