This allows you to fill in missing or additional information if necessary. Remember that the goal is to take adequate class notes, not to save paper. It is frequently not possible to write down everything the lecturer says. The average speed of talking is 125 words per minute, while the average speed of writing is about 55 words per minute. It is also not necessary because not everything mentioned in the course of a lecture is equally important.
Many instructors organize their lectures around a few major points or topics.
Each major topic is explained using several minor supporting points and examples. Record all the major topics and the minor supporting ideas that help to explain them. Instructors often repeat points using different words and several examples in an effort to help students understand the main points of the lecture. Don't get lost in the barrage of explanatory material. Stay alert to what is important.
