Wan Wei's problem is better. First of all, because the questions here are all real questions in the senior high school entrance examination, they are more representative, and there are no original questions and changes. In this case, the accuracy and busy tone of a topic are maintained, which is very in line with the current examination trend.

Secondly, because the difficulty of the questions is very moderate, that is to say, whether you are a top student or a poor secondary school student, you are very suitable to do this workbook, and you can easily find the questions you want to do from it, thus improving your exam results.
