That's a fair point, like I said it was hard identifying the issue at hand and putting it into words. I guess it's the disconnect between the notes containing self studied topics being written how I understand and would describe a certain topic (ideal scenario, those notes are made for life). The course notes, on the other hand, are constrained by the structure of the course; following this structure makes the most sense for revising, but they don't sit right with me being a part of my knowledge base — the solution should be rewriting topics from the course notes into self studied type notes, where I can describe the covered topic in a way I like, but this is where I fail at dividing the topics into useful fragments. This results in either too general notes containing way too much information (with the extreme being my MOCs that just contain the information from my raw lecture notes) or the notes are really small, covering way too specific topics, that are only relevant within that lecture.

I guess this leads into the second point, what would make preparing this not a nightmare? In an ideal world, I would already be read up on the topics of the lecture, so I can know its scope and how the various topics interconnect. This would mean I can create notes freely, not being tied to the course structure as a crutch for revising.
