I definitely recommend the complete understanding of middle school textbooks, because I stayed at home for the whole third grade and taught myself for a whole year. I bought the whole set, and there are many problems in it. When I am doing papers, I often find some questions in the complete answers of middle school textbooks, and the detailed answers are exactly what those of us who study at home want! ! I also want to thank the person who wrote this book-Xue Jinxing.

I got 635 in the senior high school entrance examination, which is 40 points higher than the score line! ! ! ! Thank you very much ~ ~ ~
