What kind of textbook is good for senior one?
In mathematics, I think it is good to use Liu Zengli's textbook to interpret the expansion and two-speed learning method. In physics, it is recommended to buy "Interpretation and Expansion of Textbooks" and "Complete Interpretation of Textbooks" by Queen Xiong. In biology, I recommend the explanation and expansion of textbooks and 1 grades 5-3. In chemistry, I think the interpretation and expansion of the textbook is good.
