How to Take Better Notes in Class: 5 Proven Methods

Taking good notes in class is one of the highest-leverage skills a student can develop. Research consistently shows that note-taking — done well — dramatically improves comprehension, retention, and exam performance. Yet most students have never been explicitly taught how to take notes. They write down whatever looks important, struggle to review those notes later, and wonder why the material doesn’t stick. This guide breaks down five proven note-taking methods backed by cognitive science, along with step-by-step instructions for implementing each one.

Why Note-Taking Method Matters

Not all note-taking is created equal. A landmark study by Mueller and Oppenheimer (2014) published in Psychological Science found that students who took notes by hand outperformed laptop note-takers on conceptual questions — even when laptop users had more raw information captured. The reason? Handwriting forces cognitive processing: you can’t transcribe every word, so you’re forced to paraphrase and synthesize, which deepens encoding.

But the format and structure of your notes matter just as much as the medium. Disorganized notes are nearly impossible to review effectively. The five methods below are all structured systems that make notes both easier to take and dramatically easier to study from later. Pair these with strong study habits and you’ll see real improvements in your grades.

Method 1: The Cornell Note-Taking System

Developed by Walter Pauk at Cornell University in the 1950s, the Cornell system is arguably the most well-researched and widely recommended note-taking method in education. It’s particularly effective for lecture-based classes in social sciences, history, and humanities.

How the Cornell System Works

Divide each page into three sections:

• The Note-Taking Column (right, ~70% of the page): Where you take notes during class using bullets, phrases, and abbreviations — not full sentences.
• The Cue Column (left, ~30% of the page): Filled in after class. Write keywords, questions, and main ideas that correspond to your notes on the right.
• The Summary Box (bottom ~2 inches): Write a 2–3 sentence summary of the page in your own words immediately after class.

Step-by-Step Cornell Note-Taking

1. Before class: Set up the page with the two-column layout and a space at the bottom. Write the date, class name, and topic at the top.
2. During class: Fill the right column with key ideas, examples, and diagrams. Don’t try to capture everything — focus on main points and supporting details.
3. Within 24 hours after class: Add questions and keywords to the left cue column. Then write your summary at the bottom.
4. For review: Cover the right column, use the cue column questions to quiz yourself, then check your answers. This is active recall built directly into the format.

The built-in review structure is what makes Cornell exceptional. The cue column turns your notes into a self-testing tool without any additional prep time. For STEM courses, the system works well for lecture material but may need adapting for problem sets.

Method 2: The Outline Method

The outline method is the most commonly used system — and when done intentionally, one of the most effective for hierarchical information. It works best in classes where the professor follows a clear structure: main topic → subtopics → supporting details.

How to Outline Effectively

• Use Roman numerals or numbers for main ideas (I, II, III or 1, 2, 3)
• Use letters or dashes for subtopics under each main idea
• Use further indentation for specific details, examples, or data

Common Outline Mistakes to Avoid

Most students who “use the outline method” are actually just writing a messy hierarchy of fragments. The key is to be intentional about levels: only one main idea per Roman numeral, and each subtopic genuinely subordinate to the one above it. If you find yourself with 15 Roman numerals in a 50-minute lecture, you’re operating at too fine a grain — group related ideas together.

After class, review your outline and add a brief question or “so what?” annotation next to each main heading. This pushes you to connect concepts rather than just catalog them.

Method 3: The Mapping Method (Concept Maps)

Mind mapping — or concept mapping — is a visual note-taking technique that represents information as a network of connected ideas rather than a linear list. It’s particularly effective for visual learners and for subjects with heavily interconnected concepts, like biology, philosophy, or political science.

How to Build a Concept Map

1. Write the central topic in the middle of the page and circle it.
2. Draw branches outward for each major concept or theme discussed in the lecture.
3. Add sub-branches for supporting details, examples, and definitions.
4. Draw connecting lines between related concepts from different branches, with a label on the line explaining the relationship.

The connecting lines are the most powerful part of concept mapping — they force you to actively identify relationships between ideas, which is exactly the kind of deep processing that improves long-term retention.

For digital concept mapping, tools like Miro, Lucidchart, or the iOS app Notability allow you to build maps quickly in class. Check out our best study apps guide for more options. For paper mapping, a blank unlined notebook works best — don’t try to map on ruled paper.

Method 4: The Charting Method

The charting method is the most powerful technique for comparative information — whenever a lecture or reading covers multiple items across the same set of attributes. History classes comparing political systems, biology comparing cell types, chemistry comparing reaction mechanisms, or economics comparing market models all benefit enormously from charting.

Setting Up a Chart

• List the categories you’re comparing across the top row (columns).
• List each item being compared down the left column (rows).
• Fill in each cell as information is covered in class.

The chart format organizes information in a way that makes gaps immediately visible — if a cell is empty, you know you’re missing something. It also creates a natural study tool: cover a column and try to fill it in from memory. For classes with heavy comparative analysis, the charting method is dramatically more reviewable than prose notes.

Method 5: The Sentence Method

The sentence method is the simplest structured approach: write each new piece of information on a new line as a complete sentence. Unlike transcription (which captures everything) or bullets (which can lose context), the sentence method requires enough processing to form grammatically complete thoughts while still being fast enough to keep up with most lectures.

It’s best for fast-paced lectures with dense factual content — law school, medical school lectures, and fast-moving STEM courses are good candidates. The method is less effective for highly visual or mathematical content.

After class, go back through your sentences and number the key facts, then add a “main point” sentence at the top of each page summarizing the most important takeaway. This hybrid of the sentence method and the Cornell summary creates a surprisingly effective review document.

Choosing the Right Method for Each Class

No single method is best for every course. A good strategy is to match the method to the content structure:

• Lectures with clear hierarchy: Cornell or Outline
• Conceptually dense or interconnected material: Mapping
• Comparative content (history, science, economics): Charting
• Fast-paced factual content: Sentence method
• Mixed lecture types: Cornell with embedded mini-maps where needed

The key is to review and adapt your system each semester. Keep your notes organized in a consistent structure — whether digital or physical — and revisit them within 24 hours of each class to reinforce the material while it’s still fresh. Use your notes as the foundation for your finals study plan and weekly study schedule.

Digital vs. Paper Notes: What the Research Says

The Mueller and Oppenheimer study mentioned above is often cited as evidence that handwritten notes are always better — but the reality is more nuanced. Subsequent research (Luo et al., 2018; Morehead et al., 2019) found that the quality of processing matters more than the medium. A student who uses a laptop with discipline and structure can match or exceed a handwriter who takes disorganized notes.

If you use a tablet for notes, a stylus-based setup like an iPad with Apple Pencil combined with apps like GoodNotes or Notability gives you the processing benefits of handwriting with the organizational advantages of digital. If you type, build in friction by avoiding verbatim transcription — force yourself to paraphrase and synthesize. And consider a pair of noise-canceling headphones to stay focused when taking notes in a busy lecture hall or library.

After Class: The 24-Hour Review Rule

Research on the forgetting curve — first described by Hermann Ebbinghaus in the 1880s and confirmed repeatedly since — shows that we forget roughly 50% of new information within an hour and up to 70% within 24 hours without review. The single most effective thing you can do after taking notes is to review them within 24 hours.

This doesn’t require a long session — even 10 minutes of reviewing your Cornell cues, re-reading your summary sentences, or testing yourself on your chart columns is enough to dramatically flatten the forgetting curve and shift the material into longer-term memory. Build this review habit into your daily routine. See our guide to creating a study schedule for how to structure daily review blocks alongside your other coursework.

Note-Taking Supplies Worth Having

Good note-taking doesn’t require expensive gear, but the right supplies help. A quality academic planner or notebook set with dedicated sections per course keeps everything organized. Fine-tip pens in multiple colors let you code-highlight important concepts during review without using a separate highlighter step.
