Basic knowledge manual of junior high school mathematics? Junior high school physics basic knowledge manual? The basic knowledge manual of junior high school chemistry contains all the knowledge points of junior high school for three years. Super comprehensive, there are also some promotion questions and previous senior high school entrance examinations. With it, I don't think it necessary to take notes. I highly recommend it. In fact, Wang Houxiong's study plan is also good, only based on the first, second and third grades, not all three years, and the cost is higher. You can also consider it and find the corresponding grade.
