The 3+3 college entrance examination reform plan implemented in 2022, the policy includes that the subjects of college entrance examination are Chinese, mathematics and English, and the subjects of high school, high school and/or level examination are selected by candidates from ideological and political, history, geography, physics, chemistry and biology.
After the reform, we should cancel the arts and sciences and adopt the "3+3" examination mode, that is, besides the number of Chinese, we should also take exams in the forms of materialization, history and geography. The qualification evaluation of college entrance examination should focus on student status, dilute household registration and avoid household registration system.
Through market research, we can increase the information and correct the prior probability, so as to improve the decision-maker's grasp of the future possibility
