Cornell notes
Cornell notes is a note-taking layout that splits each page into three parts: a narrow left cue column, a wide right notes column, and a summary row at the bottom. You take notes on the right, add questions on the left, and write a short summary, so you can later cover the notes and self-test from the cues.
The layout does the work. By forcing a cue column and a summary row, it turns a flat page of notes into a built-in self-test. You cover the right column and try to answer the cues from memory, which is active recall instead of passive rereading.
A common misconception is that Cornell notes are mainly about pretty formatting during the lecture. The value comes after class, when you go back and write the cue questions and the summary in your own words. Skip that step and you just have notes in a narrower column.
In a biology lecture you fill the right column with the steps of the Krebs cycle. After class you write cues on the left like "What does the Krebs cycle produce?" and "Where does it happen?", then a one-line summary at the bottom. The night before the exam you cover the right side and answer the cues out loud.
- 1Split each page into a narrow left column, a wide right column, and a summary strip across the bottom.
- 2During the lecture or reading, write your notes only in the wide right column, using short bullet points.
- 3Soon after, fill the left column with cue questions or keywords that match the notes beside them.
- 4Write a two or three sentence summary of the page in your own words in the bottom strip.
- 5To revise, cover the right column and answer each left-column cue from memory, then check.

Upload your lecture or PDF and Bo builds a study guide and flashcards grounded in that material, with cues and questions on one side and answers on the other, so the recall step Cornell notes are built for runs automatically. Every answer cites the exact page it came from.

Yes, for most students. Rereading is passive and feels productive without building memory. Cornell notes force you to recall answers from the cue column, which is active retrieval, and studies have linked the method to higher test scores and better critical-thinking answers.
Do I write the cue questions during the lecture or after?
After. During the lecture you only fill the right notes column so you can keep up. The left cue column and the bottom summary are written soon afterward, while the material is fresh. That review pass is where most of the learning happens.
