[good-idea]

In school, I would, chapter-by-chapter: - Underline & make notes in the margins - After finishing, write a "précis" of that chapter on an index card - Below the précis, go through the chapter again and copy over underlined passages, notes I had made and questions I had come up with while reading

Then, I'd end up with a stack of index cards for each book, which I'd keep for reference. I rarely looked back at these notes, but the 'chore' of doing this for every chapter really helped the complicated stuff sink in.
