Hi Leapyearlover I can tell you how it worked on my course. I don't know whether Jane has made any changes since then.
There were 7 weeks. Weeks 1 and 7 were a roughly 30 min 1:1 video call with Jane. The middle 5 weeks were seminar style. In my class we had Jane and 5 students. It's a video conference (via zoom), so discussion rather than typing. These were 2 hrs long, though sometimes ran over due to interesting discussions!
There is an extensive reading pack for each week of the course. You don't have to read it all. There is core reading and optional reading, and questions to answer that go on to frame the seminar discussions. I was very pushed for time during the course. I probably averaged something like 5hrs self-study per week but would have liked to do more. It is understood that we all have busy lives so it's not a problem if you haven't had time to do much reading, or look at questions, or haven't got around to a key text. Having said that, the more prep that's been done by the class as a whole, the more you can get out of the discussion. One of the things I was looking forward to after the course was reading all the stuff I had skipped over in the prep.
Last I heard Jane was considering setting up a follow-on course involving more self-study and then the two courses together could be accredited (I don't know by whom.)
On the whole I enjoyed it immensely. The course packs are brilliantly put together and cover extensive amounts of original feminist texts. On top of that, the seminars were a real treat - spending an evening with Jane and a set of other brilliant women getting into the meat of these ideas.
Hope that helps.
