What exercise book should I use for the seventh grade math edition?
Three-year simulation of the five-year senior high school entrance examination or Wang Houxiong study plan (this is a relatively mainstream exercise book, just one of the two books will do, and I prefer May 3) Qidong middle school exercise book (one exercise every day, but it will be effective if you stick to it) can buy Huanggang middle school exercise book (the topic is difficult and suitable for improvement). I often found wrong questions when I did it before, and I wonder if there is any improvement now.
