Disclosed is a knowledge point structure-based question library system, which can improve the learning efficiency of a student and enhance the teaching effect of a teacher for the student. The technical solution is: questions are set on the basis of a knowledge point structure, and the questions are associated with knowledge points. Therefore, the student can refer to and learn the knowledge points related to the questions while reviewing the questions. For questions with wrong answers, the system can also purposefully provide, for the student, all test questions corresponding to knowledge points associated with the questions with wrong answers, so that the student receives intensive training on the knowledge points corresponding to the questions with wrong answers. The system can further carry out comprehensive analysis on the questions under the same knowledge point, and provide a comprehensive analysis result for the student and the teacher, so that targeted reviewing is planned.
