I have tried this, and tt's a good pedagogical method for learning-how-to-learn, but it's inconvenient in practice I think it's worth learning how to use Anki instead. The key challenge there is selecting the right level of coarseness, so that it doesn't take forever. Even if you don't end up reviewing your cards, the act of synthesising information helps you learn it. Down the line you're able to encode important in…
That said, I think it's a good idea, but might not be for everyone. Kind of like how there are different apps like Notion, Trello, Quip, OneNote, etc., and while Notion works for a lot of people, some people benefit more from Trello's boards and cards.
