Reader comments
This book is really good! It covers the key and difficult points of High School Chemistry Compulsory Course 2, the knowledge context is clearly organized, and the exercises are also very targeted. I think it will be very helpful to improve chemistry scores, especially for people like me who have difficulty understanding chemical reactions and organic compounds. Moreover, I am also deeply encouraged to see that Xueersi has trained so many outstanding students. I think this book is not only a good helper for learning, but also an inspiration
