If it is near the senior high school entrance examination, you can choose Mathematics for Senior High School Entrance Examination 20 12, which is divided into three levels: basic questions, inquiry questions and finale questions. The blue book is edited by Zeng Dayang and Yang Jinnan, and the publishing house is East China Normal University Press, which is very detailed and has guidance for solving problems. I am a student facing the senior high school entrance examination. I like this book very much and recommend it.
