Cornell notes are a note-taking system used in Pre-AP History classes that involves three main parts - keywords, notes, and a summary. Notes are taken by writing important details, events, and people, followed by a note about what was read and a keyword to remind the reader. When finished taking notes, a one to two sentence summary is written in the bottom section to summarize the notes. Proper Cornell note taking focuses on only including relevant information in concise notes, with keywords, names, dates, places, and descriptions.
