The landlord of Hunan, Hubei and Jiangxi mathematics college entrance examination can try to challenge it.

The college entrance examination questions in these three provinces should be the most difficult in the country.

It is generally difficult to use the national volume in Henan Province.

The math problems in Shandong Province are only as difficult as the national papers.

In addition, Shanghai paper can be done, although it is not difficult, but it is a proposition reference for the provinces in the new curriculum reform and college entrance examination (sample paper, Beijing new curriculum reform and college entrance examination this year), and the difficulty of Jiangsu paper can also be done.

If science is integrated, it will challenge the national volume (many provinces with independent propositions do not have the right to integrate liberal arts and science)

The examination questions of physics and chemistry students can challenge Jiangsu paper and Shanghai paper.

Jiangsu paper is difficult, and Shanghai paper is innovative.
