I think it's best to wait until the 2022 edition, because the title of 202 1 only contains the question of 2020, and there is no question of 202 1 at all, so it is not comprehensive. After all, you are the senior high school entrance examination in 2022, so you'd better wait until the 2022 edition.

"Three-year Simulation of Five-year Senior High School Entrance Examination" is published by Education Science Press and Capital Normal University Press. The book is divided into two volumes, full practice+full solution, full solution and other answers. There is also a senior high school entrance examination version of the "five-year senior high school entrance examination three-year simulation" specially designed for students who are about to take the senior high school entrance examination.

Only for the sixth grade (Shandong Education Publishing House), seventh grade, eighth grade and ninth grade of junior high school, there are versions such as Jiangsu, Hunan, Shanghai, Sichuan, China Normal University, Beijing Normal University, East China, foreign languages, Zhejiang and Shandong. The three-year simulation of the five-year senior high school entrance examination contains all the questions in the past five years, which is relatively general and summarizes the content and questions of the textbook to some extent.

High school analysis:

China's high school education includes: ordinary senior middle schools, ordinary secondary specialized schools, adult high schools, vocational high schools, intermediate technical schools, vocational secondary specialized schools and secondary normal schools.

Senior high school education in China is non-compulsory, and students must pay necessary tuition and other fees. Since 2009, the state has implemented the tuition-free policy for senior high schools in some poor areas.

High school graduates can take the national unified examination for enrollment in ordinary colleges and universities. By May 30th, 20 16, there were 2,879 institutions of higher learning in China, including 2,595 ordinary institutions of higher learning (including 266 independent colleges). Students can choose their own schools according to their examination results.
