Difficult to understand. When I was in junior high school, I generally had high requirements for computing ability, and various methods, such as rational numbers, etc., all of which required a variety of calculations and attached great importance to the ability to solve problems, functions, etc., would use concepts and some formulas, and the next was a quadrilateral, etc., which required a complete understanding of the knowledge points before testing.

And after studying, you need to prepare for the high school entrance examination about the third year of junior high school, review all the knowledge you have learned, and need to understand all aspects of the difficulties, etc., so you need to find a certain amount of free time to review and preview the work when the house price is in place.
