(1) Remember. "Strike while the iron is hot", seize the time after class, compare books and notes, and recall relevant information in time. This is an important prerequisite for sorting out notes and providing "integrity" for notes.

(2) supplement. The notes taken in class are generally faster than the recording speed because they follow the teacher's lecture speed. So there will be ellipsis, jumping, ellipsis, conciseness and even symbols replacing words in the notes. On the basis of remembering, make timely repairs to make the notes "complete".

(3) change. Review your notes carefully and correct inaccuracies such as typos and sentences. Among them, special attention should be paid to revising the contents related to answering after-class exercises and teaching (learning) purposes, so as to make notes "accurate".

(4) editing. With a unified serial number, the contents of the notes are arranged logically according to the outline, numbered, and the order of sorting out the notes is sorted out, so that the notes are "organized".

(5) integration. Use words (preferably in red ink) or symbols, codes, etc. Classify the contents of the notes. For example, what are words, writers and works, what works (texts) are analytical, what are questions, questions and answers, and so on. Prepare to classify and abstract, and make notes "systematic".

(6) give up. Omit unimportant notes to make them "concise"

(7) remember. Classify and copy the sorted notes. Similar knowledge can be copied in the same book, or in the same part of a book, or by card classification. This makes it easy to review and use in the future, get it on demand, have a clear outline, be quick and easy to use, and make the notes "informative".
