No matter politics or history, we need to use the knowledge points in books to analyze materials. It is required to recite on the basis of understanding and further analyze the application. Attention should be paid to it. But other details and small knowledge points must also be mastered. Because there are many key knowledge points closely related to the rest, it is impossible to analyze all the problems comprehensively without mastering them. Moreover, the college entrance examination never said what key points to take. Reciting political history requires controlling the overall situation. In other words, we must master the relationship between knowledge points and recite them in outline.
