How many pages do you need for three-year single-subject notes in high school?
Look at a person. From my experience, if you are serious, patient and excellent, you will get 180 pages, and if you have principles, examples or wrong questions, you will get higher. Mathematics is used the most. It is estimated that there are two or three notebooks with 80 pages, and one in Chinese and others is enough. Really not enough to supplement! Actually, it's a matter of persistence.
