Preview before learning. Before you seriously engage in your study, first glance over what you want to learn and get to know the general content and structure of your study, so that you can understand and digest the study content in time. In important places, slow down your study a little.
Make full use of class time. It is especially important to cooperate with the teacher in class, take notes to help you remember what the teacher taught, think independently and keep up with the teacher's ideas and rhythm.
The notes made in class should be reviewed in time after class, which is not only the important content taught by the teacher in class, but also those that are still very vague. Review your notes and textbooks regularly and do some related topics.
