20 15 is it difficult to do science mathematics in Guangdong college entrance examination? Difficulty analysis

20 15 Guangdong college entrance examination for science mathematics has ended. Is it difficult to test science mathematics in Guangdong college entrance examination? Still quite relaxed? Yipin College Entrance Examination Network has compiled 20 15 Guangdong college entrance examination science math problems for your reference.

Comments on Mathematics Test Questions 20 15 General College Entrance Examination Science Mathematics (Guangdong Volume) has well implemented the proposition guiding ideology, examination contents and requirements of "20 15 General College Entrance Examination Mathematics (Science) Outline Description (Guangdong Volume)", and has continued the proposition style of Guangdong Volume, emphasizing foundation and ability. The exam questions are completely derived from.

First, boldly innovate and reduce the difficulty.

Generally speaking, the structure of the test paper (8+8+6) has not changed, but the distribution of knowledge points in the last three questions is different from the past. The overall difficulty of the test paper is slightly lower than 20 14. Fill-in-the-blank questions (1- 15) mainly focus on basic questions, with the proportion of intermediate questions slightly reduced, and the difficulty of innovative questions reduced. The first three questions (16- 18) are basically the same in difficulty. As for the last three questions (19-2 1), we changed the order of the previous series, analytic geometry and derivative, and made bold innovations. Except for the difficulty of the last question, the difficulty is generally reduced. 20 15 college entrance examination is especially beneficial to students with solid foundation.

Second, pay attention to the main double-base exam, and the innovative questions are innovative.

It can be found from the above table that Guangdong Volume 20 15 still pays attention to the examination of main knowledge, with stable test sites and double-base examination. Judging from the types of propositions, the position difficulty of conventional questions such as 8, 19, 20, 2 1 is reduced.

Question 8: On 20 15, I tested a counting problem combining spaces. Compared with previous years, the choice of innovative questions is relatively simple. Even if students can't do it, there is a great possibility of guessing the answer.

19 questions: In previous years, 19 questions were all about series. 20 15 Examining the knowledge of functions and derivatives with a new question. All three questions are relatively simple. Although the third question is an inequality proof, the inequality model involved is often mentioned in high school lectures, and the problem is not big.

Question 20:2065 438+05 Geometry problem analysis is very difficult. The first question is the old routine, which is not a problem for candidates who do solid review. The second problem model is a circle, which is easier than a cone.

Question 2 1:2065 438+05 The biggest change is the finale. In previous years, Guangdong's finale tested functions and derivatives, and Guangdong's test method won by complexity. 20 15 it is still good to abandon this model. This question examines the sequence of numbers. The first two questions are relatively simple, and the third question is comprehensive and difficult to examine inequalities.

Finally, the College Entrance Examination Research Center wishes 20 15 college entrance examination students to achieve excellent results and be admitted to an ideal university. At the same time, for the students who fought in the decisive battle of the 20 16 college entrance examination, they began to prepare for a round of review in the summer vacation of 20 15. I wish the new senior three students can experience the storm of senior three, lay a solid foundation for the college entrance examination this summer and achieve ideal results in the 20 16 college entrance examination. The author suggests that when preparing for the exam, the majority of senior two candidates should start with the teaching materials, lay a solid foundation, review comprehensively and systematically, and leave no dead ends. On the premise of mastering the basic knowledge, pay attention to reviewing the main knowledge of high school mathematics and flexibly use important knowledge such as sequence, conic curve, function and derivative. While perfecting the knowledge system, we should also pay attention to the cultivation of ability.
