(1), take notes. Notebooks are essential. It's best to prepare a separate notebook for each course, and don't write down the notes of several courses in one notebook at the same time, which will be very confusing. Prepare two pens with different colors, highlight the key points, and distinguish different contents by color.

② Draw a vertical line on the right side of each page of notes, leaving a blank of 1/3 or 1/4, which can be used to fill in the blanks after class or write your own experience. Most of the pages on the left are used for taking class notes.

③ There are various ways to take notes. The common note-taking methods used by students in class are notes, outline notes and chart notes.

Key notes: instead of recording everything the teacher said, we should grasp the key points of knowledge, such as important concepts, arguments, arguments, conclusions, formulas, theorems and laws, and summarize what the teacher said with keywords.

Outline notes: This kind of notes is based on the teacher's classroom blackboard writing. Firstly, the titles of lecture chapters are recorded, and different levels are divided by uppercase and lowercase letters according to the order of teaching content, and each level records the main points and related details. Clear organization makes people clear at a glance.
