How to Take Notes: The 5 Best Methods

There isn't one perfect note-taking system. There are five solid ones, and the right one depends on the class, the professor, and how your brain organizes information. A history lecture full of stories is different from a math class full of derivations, and your notes should reflect that.

Before you walk into your next lecture, decide on a method. A little planning here pays off all semester. The five we'll cover: outline, Cornell, mind map, flow, and write-on-slides.

The outline method is built on bullet points and hierarchy. Top-level bullets capture the main points. Indented sub-bullets fill in the details. It works beautifully when your professor moves in a clear, linear order.

On paper, leave whitespace under each main point so you can add detail later. On a laptop in something like Notion, Evernote, or Obsidian, you can reorganize bullets and nest new ones without rebuilding your page. For dense factual material, this is usually the lowest-effort method that still produces useful notes.

Developed at Cornell in the 1950s by Walter Pauk, this method divides your page into three sections. Draw a vertical line about a third of the way from the left edge, then a horizontal line a couple of inches from the bottom.

During class, write normal notes in the wide right column. As soon as you can after class, fill the narrow left column with cue questions that match each section, then summarize the whole lecture at the bottom. The structure forces you to review while it's fresh, so your notes are already exam-ready by the time finals roll around.

Start with a blank page and write your main topic in a circle in the middle. Branch off sub-topics, then branch off those. Mind maps work best when ideas connect in non-linear ways, which makes them great for brainstorming, planning essays, or studying topics with lots of cross-references.

They're less useful for fast-moving lectures where you can't keep up with the branching. Save mind maps for after-class consolidation, or for the kind of class where the professor genuinely jumps around between connected ideas.

The flow method was invented by Scott Young, the writer who taught himself the entire MIT computer science curriculum in a single year. Instead of transcribing the lecture, you build your own mental model on the page as the professor talks.

Sketch arrows between related points. Add side notes when something clicks. Write in your own phrasing, not the professor's. The goal is to actually learn the material during class, not to record it for later. Your notes will be messier, but you'll walk out understanding more.

If your professor posts slides ahead of class, print them and write directly on the printout. You get a built-in timeline because the slides follow the lecture order, and you write less because the slide already has the key points.

It's not as deep as the flow method, but for dense, content-heavy lectures it's the lowest-effort way to walk out with usable notes. Use the margins for your own thoughts and connections - that's where actual learning happens, not on the slide bullets themselves.

Match the method to the class. A history lecture full of stories suits flow. A math class with clean structure suits outline. A class with posted slides? Annotate those. A bio class with interconnected systems? Mind map.

Whatever you pick, review your notes within a day. The Cornell method bakes this in with its cue column and summary, but you can add a five-minute review pass to any system. That review is where notes turn into real memory. Without it, you're just collecting paper.
