I've answered this question many times, and it's the first time to choose the handbook of important and difficult points. I have been using it since junior high school. It has been very good for so many years, and it is my favorite teaching material. Now it is found that Longmen's notes on the number one scholar are also very good. English, history, politics and geography are all golden lists of the century. Guidance and practice, innovative design (there are many exercises in this geography, but this material is very good) By the way, in physical chemistry, there are excellent designs and two-speed training methods, which I have used and practiced myself. These are really good textbooks. Like Longmen, Wang Houxiong's textbooks are not surprisingly good teaching aids. I hope they can help you.
