The difference between Tianjin senior high school entrance examination mathematics and Hebei senior high school entrance examination mathematics: not the same test paper, Tianjin is an independent proposition, and Hebei is a national test paper. The provinces with independent propositions are completely independent test questions, and some even have scores that are not 750 full marks.

After the reform of college entrance examination, although most parts of the country use the unified national examination paper, there are still differences. In addition, some areas are implementing the independent proposition.

The college entrance examination papers are different, only in some areas. The college entrance examination papers can be divided into five categories, namely, national paper 1, national paper 2, national paper 3, semi-autonomous proposition and independent proposition. Among them, the regional volumes using the national volume are the same, but the difficulty of the national volume is different.

In terms of difficulty, national volume 1 is more difficult than national volume 2, and national volume 2 is more difficult than national volume 3. However, the topic of the autonomous proposition area is generally not too simple, at least more difficult than the national volume 3.
