The total score of science (comprehensive science) in the college entrance examination is 300, including physics 100, chemistry 100 and biology 100. The total score of science is 300, plus public subjects: Chinese 150, Mathematics 6544.

At present, only some provinces and cities in China adopt the above-mentioned form of extra-language+synthesis/synthesis, and some provinces and cities adopt the form of extra-language +X, which means that the total scores of extra-language+synthesis or synthesis of the three subjects are the same. Science includes: physics, chemistry and biology. Comprehensive literature includes: politics, history and geography. Subject to the specific provisions of this province.

Science comprehensive ability test, referred to as science synthesis or synthesis, refers to the combination of physics, chemistry and biology in the old college entrance examination. The total score of science comprehensive test questions is 300 points, among which the scores of individual subjects vary from province to province. The national comprehensive test paper is physics 1 10, chemistry 100 and biology 90.

In recent years, the proportion of biology in comprehensive management has become larger and larger, almost close to the physical and chemical score line, and others sometimes change slightly every year. That is, in the 3+X (comprehensive) exam, 3 refers to Chinese, mathematics (science mathematics) and English, and X refers to comprehensive literature composed of politics, history and geography or comprehensive science composed of physics, chemistry and biology.

There are three main aspects of losing points in the college entrance examination:

1, the exam is not allowed. Candidates can't understand the physical scene, grasp the physical characteristics and process, and grasp the physical meaning. For example, many candidates confuse "vertical height" with "acceleration distance" when sorting out 23 questions in the college entrance examination in a certain year.

2. The expression is not standardized. One is symbol confusion, such as the contradiction between the symbols set before and after or with the symbols given in the title. Write casually, and write the electronic quantity E as Q, as long as the answer is correct. Once the result is wrong, it may be implicated in the equations listed above and lose points.

3. The answer is incomplete. If there is an error in the calculation, the auditor will consider whether the equations listed above are also wrong, so the calculation process must be complete.
