Well, this mainly depends on your own needs, but I personally think that Wan Wei's large and small volumes are better, because for this material, the topics in it are all selected from some real questions in the exam, which are very representative and the answers given in it are very detailed, which is helpful for students to understand the knowledge points investigated in this topic.

Moreover, the questions here are moderately difficult and suitable for middle school students. While brushing the questions, you can consolidate the foundation, review the previous knowledge, check for leaks and fill gaps, draw inferences from others, improve the quality of complaints, exercise your thinking ability, and help top students break through the limit when doing the questions.

In the exam, you can also break through your own grades and get very high grades, which is very helpful for students' study.
