It is wonderful that your DD has a strong motivation to succeed and already uses checklists. IME you can exploit the combination to help her navigate this disorganized teachers classroom by putting a checklist in the front of her notebook/binder for that class with an expanding file (ours were made by "case it") with labeled sections for stuff to turn in, stuff required to be displayed (syllabus and class rules etc), stuff to take home, stuff to work on, etc for each class. These expanding files had 3 holes and would fit inside a notebook. If you put the checklist inside a sheet protector (or laminate it) she can see it and even mark on it and then you erase it with her that evening. Her checklist might include: turn in assignment, record board notes, record homework, pick up handouts…
The hope is that she'll form good habits and eventually (high school) not need the checklist, but it really could be used forever.

These expanding files worked really well until DD stopped using them because most of the work was online. Problem was not ALL the work was online.

Our DD never really mastered the planner in high school, but is giving it another try in college. (bought one of her own free will with kittens on it LOL)
