New! and Improved! Combo years 7/8 and 8/9

[40acres]

I'm just now realizing there's a big difference between the PDF schedule that I have and the written schedule for year 7/8. We are in week 4 using the PDF schedule. Please help me understand why all the differences. I'm looking back at the old schedule and the new schedule and neither look like the one I'm working off of? It doesn't have Bede's, Beowulf, Once & Future King, or Watership Down, and some of Term 3 is different.
