What wikipedia says about NOTES
Note-taking is the practice of recording information captured from another source. By taking notes, the writer records the essence of the information, freeing their mind from having to recall everything. Notes are commonly drawn from a transient source, such as an oral discussion at a meeting, or a lecture, in which case the notes may be the only record of the event.
Many different formats are used to structure information and make it easier to find and to understand, later. The format of the initial record may often be informal and/or unstructured. One common format for such notes is shorthand, which can allow large amounts of information to be put on paper very quickly. Note-taking is an important skill for students, especially at the college level. In some contexts, such as college lectures, the main purpose of taking notes may be to implant the material in the mind; the written notes themselves being of secondary importance.
Note-taking is a race against time. The note taker typically is under severe time pressure, and different note-taking styles and techniques try to make the best use of time. The average rate of speech is 2–3 words per second, but the average handwriting speed as only 0.2–0.3 words per second.
