I just started uploading the last video for the D.2 lessons.
As I mentioned in the previous post, updates for the B.2 summary sheet, video solutions for the new B.2 exercises, and summary sheets for D.1 and D.2 are still forthcoming, as will be exercises for the D.1 and D.2 lessons, somewhat later.
My plan is that the next things that will be posted will be the first few lessons for D.3.
