In recent years, the pattern of science has undergone very subtle changes, mathematics has attracted more and more attention, and more and more attention has been paid to the selection of talents, on the contrary, physics and chemistry have been stable, especially physics, which has gradually distanced itself from mathematics in terms of difficulty and distinction.
Mathematics has been reduced from 22 questions, the number of questions has been reduced, giving students more time to think, the weight and difficulty of optional filling have been reduced, the chancefulness of the exam has been reduced, and the number of large questions has been reduced but the score is higher and more differentiated.
All kinds of question types in mathematics, the biggest chance is undoubtedly to fill in the blanks, the choice of answers can be confirmed after calculation, the possibility of mistakes is small, and the big questions are scored according to the steps, which can better reflect the degree of discrimination, a five-point fill-in-the-blank question, not at all, and only do the last step wrong, there is no difference, on the contrary, it takes more time to make the answer, and in the state of the examination room, time is extremely precious, if you can't do the answer, but think about the idea of solving the problem, but the child who makes a mistake in calculation suffers more.
Reduce the number of fill-in-the-blank questions, reduce the difficulty of the questions, and place the score in the calculation of the step-by-step score, which is relatively more reasonable.
Multiple choice questions are less than one question, but each question is set with one more point, which also improves the degree of discrimination, mainly reflected in the fact that if there are three answers, two points are awarded for one correct one, and four points are awarded for two, so that in the state of seeking stability, the choice of two correct answers can get a 4-point guarantee, instead of the previous two points, in the case of three answers, choose one and two correct answers, from the same two points, to the difference between two points and four points, which is relatively more reasonable.
The most important change is that the big question has changed from six questions to five questions, but the score has increased from 72 points to 77 points, which is no longer the standard configuration of 12 points, but according to 13 points, 15 points, 15 points, 17 points, 17 points, the difficulty and score value increase, the score ratio of the finale question and the small question has increased from 2.4 times to 3.4 times, and the advantage of doing difficult problems has increased, not compared to the speed of doing the problem but compared to the ability of independent thinking, especially this year's finale custom question type reverse brush question mode, control the number of high scores, and can get high scores of real mathematical talents.
