In fact, in the college entrance examination in 2003, not only in Jiangsu province, but also in the whole country, the math papers were "epic" difficult: because Jaco, a candidate from Nanchong, Sichuan, stole the college entrance examination papers before the college entrance examination when he could have been admitted to ordinary colleges and universities, so that all the math papers in the national college entrance examination were replaced by backup papers, which greatly improved the difficulty.
The reason why Jiangsu paper is difficult in mathematics;
1, there are no multiple-choice questions in mathematics in the college entrance examination.
Jiangsu college entrance examination mathematics has no multiple choice questions. Jiangsu paper for you 14 fill in the blanks and warm them up first. Perhaps the 20 19 fill-in-the-blank question in Jiangsu paper is not much more difficult than the multiple-choice questions in other provinces, but there is no option to rule out, and there is a 25% chance that you can't go wrong or not.
The difficulty of answering multiple-choice questions and fill-in-the-blank questions can be described as worlds apart. Sometimes filling in the blanks is even more difficult than solving problems, because there is at least one process point in solving problems, and filling in the blanks only depends on the results.
In Jiangsu, where the total score of the college entrance examination is only 480, 5 points can be said to be more precious. Take 20 18 science as an example. The investment line of Nanjing University is 39 1, Southeast University is 388, and Nanjing University of Science and Technology is 378. It can be said that the gap between universities at all levels is the distance between one or two fill-in-the-blank questions.
2. The big science questions are difficult and the multiple-choice questions have low scores.
However, due to the difference between fill-in-the-blank questions and multiple-choice questions, the time left for big questions is at least 10 minutes. The scores of big questions in Jiangsu are high, mostly between 14 and 16. The most terrible thing is that the steps of solving problems are complicated.
There are two problems in the score of 14 and three problems in the score of 16. An extra problem needs 2 points, which is really tangled. This year's first multiple-choice question can be said to be more conscientious and sub-topic.
The final choice of questions can be said to be less difficult (10). You can search the standard answer. It takes half a day just to read the standard answers and sort things out. 10 is as difficult as 16.
3. Knowledge points are close to college mathematics.
It is generally necessary to master the knowledge of mathematics in Jiangsu middle schools. After reading the mathematics volume of Jiangsu college entrance examination, many topics are really the combination of high numbers, line generation and probability statistics that universities can only see.
Vector, various curves, derivatives, matrix transformations and various combinations of knowledge points such as eigenvalues, polar coordinates and random variables. The most difficult thing is that the big problem behind Jiangsu mathematics is developing towards a comprehensive analysis problem. For example, in the answer to the question 18, the positions of point P and point Q were discussed many times, and the questions were investigated to see if you could consider them comprehensively. If you are not careful, you will miss something.
I just don't know what the specific score is. If the first two questions can get more than 10, I will leave the third question to the last one, because the effort is not proportional to the gain.
