In the long run, you need to choose more guidance books with flexible topics, rather than a large number of reference books to consolidate basic knowledge. Therefore, I suggest buying Focus Classroom (with a large number of topics, it is recommended to have enough time to do it), experimental classes (with flexible topics, it is recommended to leave answers) and Xue Hai Storm (the biggest advantage of this book is that it has regional sources, conforms to the local senior high school entrance examination, and also has teaching material analysis, so it is a very good book).
