Don't use "five three". It is not appropriate to use "five three" in high school. You can start doing "May 3rd" next semester. Personally, I think it's not very good. Isn't there Wang Houxiong? Wang Houxiong's question is enough, but only if you do it seriously. Some of the questions there are really basic and some are difficult, but the analysis is comprehensive and there are few mistakes. . . . Wang Houxiong is the best in mathematics; Like the well-received exercise books on the market, there are Rong, Hong Gou, and so on. Now most senior high schools compile their own exercise books and print them themselves. You'll know when school starts. You'd better not buy too many exercise books, because the school can't finish them. The daily homework is written in 1 1. . . . .
