It is not just a structure for organizing your notes. Because of how the notes are taken and integrated with existing notes (using the elaboration, cuing, and recall test), you are actually encoding your thinking about the notes in the structure of the notes. Therefore, when you return to the notes, you are not just seeing what you wrote... you are seeing what you THOUGHT about what you wrote, which makes it easier to pick up on what you were thinking. It's not a system designed for college students trying to get a good grade on a test. It's a system designed for people who are making innovative progress on ground-breaking designs, using best information from a wide variety of disciplines. The cross-pollinization of ideas is really where it shines.
