What is the Cornell note-taking method?
The Cornell method was developed in the 1950s by Walter Pauk, an education professor at Cornell University, and later described in his book How to Study in College. It splits one page into three parts, so the same sheet works for taking notes, testing yourself and reviewing.
- Notes (the big right column). Write during the lecture or while you read. Short phrases, not full sentences.
- Cues (the narrow left column). After class, turn each block of notes into a question or a keyword.
- Summary (the bottom). Two or three sentences in your own words about the whole page.
How to take Cornell notes, step by step
Pauk described the method as five steps, often called the five R’s.
- Record. During class, write the main ideas and facts in the notes column. Leave a gap between topics.
- Reduce. Within a day, write a question or cue next to each idea, for example “What does chlorophyll do?”.
- Recite. Cover the notes column and answer the cues out loud. Check what you missed.
- Reflect. Ask yourself how this connects to what you already know, and write the summary.
- Review. Spend a few minutes each week answering the cues again, especially before a test.
An example
Chlorophyll absorbs light, mostly red and blue; reflects green.
In: CO₂ + water + light. Out: glucose + oxygen.
Happens in chloroplasts, mainly in leaf cells.
Tips that make Cornell notes work
- Write the cues as questions. A question makes you recall the answer, which helps far more than rereading.
- Do the cues and summary the same day. Your memory of the lecture is still fresh, so gaps are easy to fill.
- One topic per page. Start a new page for a new topic. It makes review much faster.
- Use it for reading too. The method works for textbook chapters and online articles, not only lectures.
Questions
How big should each section be?
The classic layout on US Letter paper is a 2.5-inch cue column, a 6-inch notes column and a 2-inch summary at the bottom. Choose a wider cue column if you like to write full questions.
Does the Cornell method really work?
Studies of the Cornell format itself show mixed results. The habits it builds in, testing yourself with questions and reviewing soon after class, are among the best-supported study strategies.
College ruled or wide ruled?
College ruled lines are about 9/32 inch (7.1 mm) apart and fit more text. Wide ruled lines are about 11/32 inch (8.7 mm) apart and are easier if you write large.
Can I use Cornell notes for math or science?
Yes. Put worked examples in the notes column and the type of problem or the formula as the cue. Choose the grid ruling for math.
Can I fill in the template on a tablet?
Yes. Download the PDF and open it in any note app that lets you write on PDFs.
