Guides · Note-taking
The layout is simple. The reason it works is that it forces you to process your notes twice, and the second pass is where the learning happens.
Most students take notes in a single stream down the page: whatever the teacher says, in the order they say it. This is fine for capturing information and terrible for reviewing it. A week later the page is a wall of text with no signal about what mattered, and "studying" becomes re-reading the whole thing.
The Cornell method, developed at Cornell University in the 1950s, fixes this with a page layout that has three areas instead of one. The layout itself is not magic. What makes it work is that each area is filled in at a different time, which builds review into the way you take notes.
Divide the page into three regions:
The Cornell Notes Template on this site gives you this layout in the browser and saves each page so you can come back to it. On paper, a ruler and two lines do the job.
Write in the notes column the way you normally would, with a few adjustments:
This is the step that most students skip, and it is the one that makes the method work. Within a day of the class (ideally the same evening), go back through the notes column and, for each chunk of notes, write a question in the cue column that the notes answer.
If your notes say "light rxn in thylakoid, makes ATP + NADPH," your cue might be "Where does the light reaction happen and what does it produce?" If your notes cover the causes of the First World War, your cue might be "4 long-term causes of WWI?" A single page usually ends up with five to ten cues.
Two things are happening when you do this. First, you are re-reading your notes while they are fresh, which catches gaps and unclear abbreviations before you forget what they meant. Second, and more importantly, you are converting your notes into a self-test. See the next section.
Some students write keywords instead of questions in the cue column. Questions are better. A keyword like "light reaction" prompts recognition. A question forces retrieval.
At the bottom, write two or three sentences that summarize the entire page in your own words. This is harder than it sounds and that is the point. If you cannot summarize a page, you do not understand it yet, and it is better to find that out now than during the exam.
A good summary is not a list of topics ("This page covered photosynthesis, the light reaction, and the Calvin cycle"). It is a statement of the idea: "Photosynthesis happens in two stages: the light reaction captures energy as ATP and NADPH in the thylakoid, and the Calvin cycle uses that energy to build sugar from CO2 in the stroma."
Here is where the layout pays off. To review a page, cover the notes column with a sheet of paper (or, in the template, collapse it) so only the cue column is visible. Go down the cues one at a time and answer each from memory, out loud or on scrap paper. Then uncover the notes and check.
This turns every page of notes into a ready-made active recall session with zero extra preparation. A page takes two or three minutes to review this way. A week of lectures takes fifteen. Repeat on the spaced schedule and you will walk into the exam having retrieved every idea from memory four or five times.
Outlining and mind mapping are both good, and the Concept Map Builder is worth using for topics where the connections matter. But both are hard to do well in real time during a fast lecture, and neither produces a self-test automatically. Cornell notes are forgiving during class (just write) and structured after class (cues and summary), which is the right way round for how attention actually works. The whole post-class process takes about ten minutes per page, and it replaces hours of re-reading later.
