A: Time is divided according to the score ratio of the three subjects and allocated accordingly. Physical chemistry takes about an hour, and biology takes about half an hour. Of course, if a subject is difficult. Or the score of a certain subject is a little more than that, and it takes a little more time.
2. Will it be more difficult to organize this year? Will the proportion of science, culture and life change?
A: The proportion of science, chemistry and biology is roughly equivalent to the proportion of the total class hours of the three subjects stipulated in the current curriculum plan of middle school, which is about 4:4:2 (generally speaking, the composition of the paper should be based on the actual situation of serving the test questions)
The difficulty of the test questions is roughly as follows: difficult questions account for about 20%, medium questions account for about 50%, and easy questions account for 30%. The average difficulty of all questions is based on the principle that the whole test paper can distinguish candidates to a great extent.
3. What are the percentages of physics, chemistry and biology in "3+X"?
A: If there is a ratio, the old textbook is about 4:4:2, and the new textbook accounts for about 37% of physical chemistry and 26% of biology. This is an important reference for the comprehensive ratio of 200 1 college entrance examination. Because the college entrance examination is to seek reform and innovation in maintaining stability, but stability is the key and prerequisite. In fact, the proportion of college entrance examination is stipulated in the curriculum plan of middle school, and the proportion of the three subjects in the total class hours is roughly the same.
