Compare Note-Taking Systems for Study

You've tried a few note-taking methods and none of them stuck, so you're back to messy margins. This compares the four big systems, Cornell, Zettelkasten, mind mapping and outlining, against your actual subject. You get the layout, the review habit and the upfront effort for each, then a recommendation rather than a shrug.

<context>
You want to build a consistent note-taking habit for studying or self-directed learning. You have tried a few approaches but nothing has stuck. Your subject area is {SUBJECT}.

<task>
**Compare the four main note-taking systems for your context:**
1. Cornell Method: layout, how to review, best subject types
2. Zettelkasten: atomic notes, linking ideas, upfront effort vs long-term payoff
3. Mind mapping: when visual structure helps, when it fragments understanding
4. Linear outlining: speed, compatibility with typed notes, easy recall

**For each system:**
- Time cost per session
- Review efficiency
- Best fit: passive recall vs active application

**Recommend one system** for the subject type and how to start it this week.
