The On My Own pages list the things on the main schedule page that a student should do on their own (as opposed to being read aloud to, etc). So it is partial repetition.
The readings do go from book to book. I tend to read bigger chunks out of one or two books one day, then do another book or so the next day. We just prefer it that way. I look at what I need to cover for that week, and I group it how it works for me. But the guidebook gives me the goal for the week, and it is organized so I know what to do when, if that makes sense.
