Under the "3+ 1+2" model, candidates must choose history, physics 1 subject, and ideological and political science, geography, chemistry and biology.
When calculating the scores of the college entrance examination, Chinese, mathematics, foreign languages, physics/history are presented as original scores, and the original scores of the other four subjects (ideological and political, geography, chemistry and biology) are converted according to unified rules to form an average score, which is included in the total score of candidates.
Before grading, candidates' test scores are the original scores, and the final scores can be obtained through the conversion of grading, and the final scores are included in the college entrance examination scores.
The new college entrance examination breaks the traditional division of arts and sciences and provides students with 12, 20 or even more choices, while students who choose different combinations can apply for the same major in the same university. Because no one can balance the difficulty of different subjects, it is relatively the fairest way to implement the scoring system.
Under the new college entrance examination, college entrance examination students choose different subjects, and there are differences in content, form, difficulty and examination angle between different subjects. The simple addition of the original scores of various subjects will cause unfairness among disciplines.
In order to make up for this deficiency, the grading system can objectively reflect the ranking and level of student A in choosing chemistry and biology, the difficulty of examination questions, and the ranking and difficulty of examination questions of student B in choosing geography and politics.
The grading system was born to solve the above disadvantages. It effectively overcomes the problem that different subjects are comparable due to different groups of candidates and different test papers, which are converted into grades through rules and ranked as the standard. It is not judged by scores, but by the ranking of individual subjects in the overall ranking.
