70. 13. According to official website of Sichuan Education Bureau, in 20 14 years, the average score of mathematics in Sichuan college entrance examination was 70. 13, in which the average score of liberal arts was 74, the average score of science was 80, and the difficulty coefficient of test questions was 0.505. In addition to the difficulty of adjusting and controlling the proposition group, the change of test question structure and the difficulty of marking papers also have an impact, and the average score has dropped significantly. However, the selection, discrimination and scientificity of the test questions are more reasonable than last year, which does not violate the principle of maintaining stability and scientific selection.
