1, "Entering the High School-Training of Excellent Mathematics Lectures"
If you want to do a difficult and difficult question, you can have a look. It is more suitable for children who have a good foundation and want to improve themselves, but have a large number of questions, just to train the speed of doing questions.
2. Qidong Middle School Exercise Book
The difficulty is not great, but the overall feeling of the topic is very good, which is suitable for doing problem sets. The topic is standardized and representative, and the number of questions is not much. Draw inferences from others.
3. "Must Brush"+"Crazy K Focus"
Generally speaking, the quality is good, and the types, quantity and difficulty are obviously ahead of schedule. One can play the role of brushing questions.
4. Textbook help
Generally speaking, I feel more like a "must brush topic", which is quite good. The topic is relatively new and then typical (but the new topic is not necessarily a good thing, many topics have changed their forms, and now some topics are very strange).
5. First assignment+first assignment: unit test paper
There is one of the most obvious shortcomings: a large number of questions. It divides a knowledge point into several sections. If you follow the school, you can't keep up with the rhythm. It is easy to give up this sport. It is recommended to review in winter and summer vacations, but the topic feels simple and can be used to consolidate.
6. "Classroom exercises"
Typesetting is very simple and practical. Because it looks simple, I feel that I can go out to play soon. The topic is very classic, and it is still very suitable for starting, but I only saw the Shanghai Education Edition for the time being.
