3+2 is the five disciplines of physics and chemistry outside the language, with a total score of 150 points, and the two disciplines of physics and chemistry have the same weight as the three main subjects, but biology is not used as a scoring subject in the college entrance examination, and only needs to pass the examination.
However, the entrance examination was much more difficult than it is now, and a considerable number of candidates were eliminated from the examination and could not take the college entrance examination. Therefore, although it is a minor subject, biology and geography still need to invest time to learn.
The total score of 3+ science and chemistry is 300 points, and the physics and chemistry are in the same volume, but the weight of physical chemistry is higher than that of biology, but the score of a single subject is lower than 150 points, but higher than 100 points. From 3+2 to 3+, the physical and chemical scores have been reduced, and the reduced scores are given to organisms, and organisms begin to enter the scoring content.
However, Jiangsu Province has entered the mode of only taking the total score of 480 points in addition to the number of languages after 3+ science and science, and the materialization exists as a grade score, and the weight of physics and chemistry is almost zero, which only exists as a form of grade assessment, which makes students with good scientific thinking not only have greater pressure on the college entrance examination results, but also fail to lay a disciplinary foundation for university study.
The 3+1+2 form is close to the fusion version of the 480-point model of science and science, with 100 points for physics and history, and other disciplines for assigning points, for Jiangsu candidates, other disciplines other than language and mathematics have begun to have weights, and for the original provinces of science and technology, the total score of physicochemical biology is the same as 300 points, but physics and chemistry are higher than biology, and the three are equal. However, the weight of materialization decreases and the weight of organisms increases.
Although the same score is 100 points, before the physicochemical bundling, the weight of chemistry is the most among the three disciplines, and physics is the original score is included in the grade, while after the assignment of chemistry and biology points, the score difference is often significantly reduced, and the actual weight is smaller than that of physics, and due to the difficulty of chemistry, the abandonment of chemistry is obvious, which makes chemistry the most neglected in the nine disciplines in high school, and the selection is much smaller than that of other disciplines, while after the physicochemical bundling, the weight of chemistry has been improved to the same level position of other disciplines.
