I like to take my notes hierarchically where possible. A lot of things you take notes on, especially in class are concepts that depend on each other. The point being that when you read the notes back to yourself later you'll know that concept Y has a relationship with concept X. Or further Concept Z depends on Y depends on X So the note structure is something like this - X -- Y --- Z
