Practical steps of the three-layer note-taking method:
Conception NotesSealed NotesAction Notes

Conception Note

[Output] Move the actionable or most crucial content extracted from the conceptual notes layer to the action notes layer, so that every time you open your note document, you can directly focus on the key points.

Sealed Notes

[Collect] In the conceptual notes layer, jot down instant ideas, outlines, meeting records, or annotations on your study materials.

Action Notes

[Sorting] As your "just-in-time" notes accumulate, you can transfer any excessive or less important content from the conceptual notes layer to the archived notes layer, ensuring that the conceptual notes layer retains essential content, while the archived notes layer serves as supplementary information for reference.
