The provinces and cities used in the second volume include Gansu, Qinghai, Inner Mongolia, Xinjiang, Tibet, Liaoning, Heilongjiang, Jilin, Ningxia, Shaanxi and Chongqing.

Different from the provinces that use the national 1 volume, the provinces and cities that use the two volumes are mainly the underdeveloped areas in the west and the three northeastern provinces.

Generally speaking, the development of education in the second volume area is obviously not as good as that in the 1 volume area, so the difficulty of the second volume is often lower than that of 1 volume. This institutional arrangement can better reflect the fairness of the college entrance examination and is reasonable.

From a national perspective, 20 19 college entrance examination papers are more difficult than 20 18. Therefore, even the relatively simple national second volume will be more difficult this year than last year, which is an intuitive reflection of the trend.

Judging from this year's math test paper, it is generally reflected that the difficulty of the two-volume math test paper is higher than last year, which also proves that the changing trend of the difficulty of the test paper is established.

For the national two-volume examination paper, the difficulty feeling should be the actual feeling of the candidates in the use area; It is more objective and reliable to compare its difficulty with the two volumes in previous years.

Extended data:

The difference between the first and second volumes of the national college entrance examination is 1, and the difficulty coefficient is different: the degree of discrimination is increased according to the difficulty coefficient of the question type. The difficulty coefficient of China Volume I of the new curriculum standard is higher than that of China Volume II, and the competition pressure of candidates in areas where China Volume I is used is greater. The competitive pressure of candidates in the second district of the national volume is relatively small.

2. The content of the question is different: the English in the first volume of the whole country is listening, but it is not in the second volume of the whole country. There are ten word-filling questions in the second national volume, but there are none in the second national volume. ..

3. Different application provinces: Henan, Hebei, Shanxi, Jiangxi and other places use the national volume I, while Qinghai, Tibet, Gansu, Inner Mongolia, Xinjiang, Ningxia, Jilin, Heilongjiang, Yunnan, Guangxi, Liaoning and Hunan use the comprehensive management and language of the national volume I. The second volume covers Ningxia, Gansu, Xinjiang, Inner Mongolia and Tibet.
