The whole book was published after the outline of the official tutorial 10 came out. The mechanic section in the general forum mainly talked about this tutorial. The fascicle is a detailed review book written by some teachers and published in the first half of the year. Personally, I feel that English books are very general, and one is not big. Mathematics is still based on textbooks, and volumes can be used as a supplement. The combination of logical points of logical volume and mechanical version is almost the same.
