Studying in advance allows us to explore chapters that the teacher has not talked about. Because I haven't studied it, I will look at the concepts and examples carefully. It doesn't matter even if we don't understand them. The process of exploring the unknown knowledge will take root in our minds, and once there is something to stimulate it, it will come back to life. After coming into contact with this knowledge point, it will be easy to achieve mastery through a comprehensive study.

Benefits:

Because the previous knowledge point is the relationship between points, lines and surfaces. Even the context of knowledge will be intertwined, which is the ability formed after mastering comprehensive knowledge. If you study a book or several books in advance, you will have a more comprehensive knowledge. When it comes to a knowledge point, you can associate it with related knowledge points, thus giving inferences.

Disadvantages:

Because of studying in advance, students are not interested in the class, feel that they have mastered the content of the class and are unwilling to listen to the teacher. This is also an important reason why the education sector opposes advanced learning.

Students who study in advance think they have mastered what they have learned, but in fact they may only have mastered 80% of the knowledge points. Because they don't listen carefully in class, it's easy to miss the 20% knowledge points.
