What book should I use to brush the math problems in junior high school?
"5.3", "Guidance", "Golden Paper" and "45 sets of papers" are all good.
45 sets of volumes are more suitable for the review stage.
It usually depends on the personal level of the landlord. Just brush the topic "5.3" or "golden paper" in large quantities, and it is better to check for leaks and fill gaps.
