First of all, because this book itself is aimed at people with weak foundation, you don't have to worry about reading it at all.
There is also a comprehensive test center inside. The general review stage is really a race against time, but the teacher's class is like feeding a "pot of rice", and it is impossible to fully take care of everyone's feelings. If you don't lay a good foundation in the first and second days of junior high school, you won't be able to keep up with the rhythm and understand. But the knowledge points are to be tested in the senior high school entrance examination, so at this time, you can take out four rounds of review of mathematics in the senior high school entrance examination. If you don't understand any knowledge points, turn to the corresponding chapter for review.
Xueba can become Xueba because they know how to choose key exercises when doing problems, while the small three parties with poor foundation basically waste their time on non-key points. What I like best is to divide the knowledge points into key points and find out 44 1 test sites with more times from 2094 available test sites. This will make it clear at a glance which knowledge points should be reviewed and which should be reviewed once.
