So the double booking was solved by giving me an online section of one course instead of the physical one at the impossible time. I have an online version of this course already built, but will need to create new material for a new unit (on Watchmen) that I've been planning to incorporate this year in the face-to-face version, and will need to revise quite a few pages. Oh well. I still have five days per week, and an evening class, but at least the back-to-back and three classes in one day and conflict have been removed.
