I do have a book that can suggest that {problem-solving decision} be divided into two thick black covers, but not only for the content of senior two. There are classic examples, which are difficult to break through in analysis. You can find the content knowledge of the second year of high school for targeted practice.

There is also a book called "Research on Test Questions", which is very thin, but rarely analyzes the topic in detail, and the topic is also very affordable, about 7 yuan a book.

At the same time, there are teaching material analysis Wang Houxiong's lesson plans.

I suggest you choose a test question to investigate others, or you can check that Taobao is sold in general physical stores.

Finally, I wish you progress in your study.
