Our (20 16 college entrance examination students) curriculum has changed, the papers we have done have also changed, and the types of questions have also changed. After the national volume 2, it was found that the curriculum could not keep up with the original, the language did not matter, and the English listening reform was independent.

The fact is, I can read books clearly. No one can predict the future. If you are not a student, don't answer this question.

Personally, Sichuan is ready to connect with the whole country and prepare two sets of national volumes, but there are problems. For example, biological experiments in Sichuan are different from those in the whole country. We learn acetic acid bacteria and yeast, and they also make fermented bean curd! There is a big difference, so I can't live without comprehensive study and mathematics. English is a reform to restore listening this year, and listening questions must be prepared by yourself. English is also written in Sichuan.

Chinese National Volume 3 has many papers. According to the types of regional exams, there are many kinds of 3+X. Even if there is news at that time that there are any missing questions, you can take out another paper immediately, so it is not what paper to take, but which region to take.
