These two books are better than Xue Jinxing's, while Xue Jinxing has few knowledge points, and the typesetting is not good in many places. Leave a number in the formula to wrap, or 2-3 words in one line, but the sort of 1234 does not wrap, which looks awkward; Besides, Xue Jinxing's book is really unpleasant when it comes to the theme. It doesn't give you a topic, but tells you what knowledge points to test, just like a high-rated question, which is full of nonsense and the first one is excluded.

The structure of knowledge list is the same as that of teaching materials, while the list of chapters with large amount of knowledge is the same as that of teaching materials, except that the classification of each chapter is a list of knowledge points, and both of them have their own advantages. A lot of the content in the article is exactly the same, and it feels a bit like copying each other. As for who copied who, it is not clear. In terms of definition, the encyclopedia of knowledge talks a lot, and its typesetting is also very regular, which is as standardized as the university textbooks, but the text is dense, and some key points may be ignored by you, so it is necessary to carefully scrutinize the deep meaning of some keywords. The definition of knowledge list is too colloquial, which is aimed at junior high school students, but it is well listed in the table, especially some illustrations, which are humorous and can help students understand quickly, much better than knowledge encyclopedia! But the definition of Qu Yixian is really too few words, always listed. Sometimes I feel like I'm going to die if I say more. ! There are also some ways to talk about topics, which are also expressed directly in formulas, so that you don't seem to understand. Both of them have defects, so it would be better if they could be combined.

I think if you are not short of money and are not afraid to spend some time, you'd better buy both sets, adding up to 200 yuan. . . If you want to read a chapter, first look at the definition of knowledge encyclopedia, which is very standard; After reading it, look at the list and illustrations of the knowledge list to deepen your understanding; Next, look at the example of knowledge list; Finally, look at the example of knowledge encyclopedia. . . When choosing a book, I have repeatedly compared several chapters, and both books are a little lacking. It is better to combine them and read them in this order. . . A complete knowledge book has a set of summaries of mathematics, physics and chemistry, which is a little more difficult than a single book. It is more appropriate to read this book after learning it all.
